An efficient implementation of Scalable Bayesian Rule Lists Algorithm, a competitor algorithm for decision tree algorithms; see Hongyu Yang, Cynthia Rudin, Margo Seltzer (2017) <https://proceedings.mlr.press/v70/yang17h.html>. It builds from pre-mined association rules and have a logical structure identical to a decision list or one-sided decision tree. Fully optimized over rule lists, this algorithm strikes practical balance between accuracy, interpretability, and computational speed.

Generates synthetic versions of numeric, categorical, mixed-type and time-series data. Marginal distributions are modelled with interpolated empirical quantile functions and dependence with Gaussian or Student-t copulas (Sklar, 1959). Discrete and categorical variables enter the copula through the distributional transform (Ruschendorf, 2009, <doi:10.1016/j.jspi.2009.05.030>), and their latent correlations are estimated by maximum likelihood as polychoric (Olsson, 1979, <doi:10.1007/BF02296207>) and polyserial (Olsson, Drasgow and Dorans, 1982, <doi:10.1007/BF02294164>) correlations. Unordered categories are placed on their latent coordinate in an order estimated from their association with the other variables. Missing values are modelled by missingness indicators inside the copula, so that missingness may depend on other variables. Supports stratified models, a closeness parameter with calibration to a target distance or disclosure-risk level, chunked generation of very large data sets, optional hybrid copula and conditional CART or GAM synthesis for one continuous response (requiring rpart or mgcv'), training-only automatic selection of the conditional engine, experimental nominal conditional synthesis of one unordered categorical response (requiring nnet'), copula vector-autoregressive and bootstrap time-series synthesis, augmentation of small training sets for machine learning, and random generation from multivariate distributions and elliptical and Archimedean copulas. Fidelity, utility and disclosure risk are assessed with marginal distances, association matrices, propensity score mean-squared error (Snoke et al., 2018, <doi:10.1111/rssa.12358>), confidence-interval overlap, correct attribution probability and distance to closest record, with ggplot2 visualisations. Data can be read from and written to CSV, TSV, RDS, RData, Parquet, Feather, HDF5, JSON, NDJSON, Excel, SPSS, Stata, SAS and fst files. The empirical-quantile and copula approach builds on ideas of the synthesizer package by Mark van der Loo.

This package performs mutational signature analysis for tumors profiled by targeted sequencing. Unlike the canonical analysis of mutational signatures, SATS factorizes the mutation count matrix into a panel-context matrix (measuring the number of mutation opportunities per million base pairs for each tumor), a signature profile matrix, and a signature activity matrix. SATS also calculates the expected number of mutations attributed to each signature, namely the signature burden, for each tumor profiled by targeted sequencing. For more details see Lee et al. (2024) <doi:10.1101/2023.05.18.23290188>.

Analysis Results Standard (ARS), a foundational standard by CDISC (Clinical Data Interchange Standards Consortium), provides a logical data model for metadata describing all components to calculate Analysis Results. <https://www.cdisc.org/standards/foundational/analysis-results-standard> Using siera', ARS metadata is ingested (JSON or Excel format), producing R programmes to generate Analysis Results Datasets (ARDs). Supports arbitrary-depth table structures, multi-value conditions, data-driven groupings, and CDISC-compliant ARD column stamping.

This package provides a modification of the preventive vaccine efficacy trial design of Gilbert, Grove et al. (2011, Statistical Communications in Infectious Diseases) is implemented, with application generally to individual-randomized clinical trials with multiple active treatment groups and a shared control group, and a study endpoint that is a time-to-event endpoint subject to right-censoring. The design accounts for the issues that the efficacy of the treatment/vaccine groups may take time to accrue while the multiple treatment administrations/vaccinations are given; there is interest in assessing the durability of treatment efficacy over time; and group sequential monitoring of each treatment group for potential harm, non-efficacy/efficacy futility, and high efficacy is warranted. The design divides the trial into two stages of time periods, where each treatment is first evaluated for efficacy in the first stage of follow-up, and, if and only if it shows significant treatment efficacy in stage one, it is evaluated for longer-term durability of efficacy in stage two. The package produces plots and tables describing operating characteristics of a specified design including an unconditional power for intention-to-treat and per-protocol/as-treated analyses; trial duration; probabilities of the different possible trial monitoring outcomes (e.g., stopping early for non-efficacy); unconditional power for comparing treatment efficacies; and distributions of numbers of endpoint events occurring after the treatments/vaccinations are given, useful as input parameters for the design of studies of the association of biomarkers with a clinical outcome (surrogate endpoint problem). The code can be used for a single active treatment versus control design and for a single-stage design.

We develop a new class of distribution free multiple testing rules for false discovery rate (FDR) control under general dependence. A key element in our proposal is a symmetrized data aggregation (SDA) approach to incorporating the dependence structure via sample splitting, data screening and information pooling. The proposed SDA filter first constructs a sequence of ranking statistics that fulfill global symmetry properties, and then chooses a data driven threshold along the ranking to control the FDR. For more information, see the website below and the accompanying paper: Du et al. (2023), "False Discovery Rate Control Under General Dependence By Symmetrized Data Aggregation", <doi:10.1080/01621459.2021.1945459>. Some optional functionality uses the archived R packages â hugeâ and â pfaâ , which are not available from CRANâ s main repositories.

Automatic generation and selection of spatial predictors for Random Forest models fitted to spatially structured data. Spatial predictors are constructed from a distance matrix among training samples using Moran's Eigenvector Maps (MEMs; Dray, Legendre, and Peres-Neto 2006 <DOI:10.1016/j.ecolmodel.2006.02.015>) or the RFsp approach (Hengl et al. <DOI:10.7717/peerj.5518>). These predictors are used alongside user-supplied explanatory variables in Random Forest models. The package provides functions for model fitting, multicollinearity reduction, interaction identification, hyperparameter tuning, evaluation via spatial cross-validation, and result visualization using partial dependence and interaction plots. Model fitting relies on the ranger package (Wright and Ziegler 2017 <DOI:10.18637/jss.v077.i01>).

This package provides an automated routing engine for longitudinal missing data. It utilizes a Lagrange-constrained Random Forest based on sample size, missingness rate, and skew to preserve structural variance.

Stepwise regression is a statistical technique used for model selection. This package streamlines stepwise regression analysis by supporting multiple regression types(linear, Cox, logistic, Poisson, Gamma, and negative binomial), incorporating popular selection strategies(forward, backward, bidirectional, and subset), and offering essential metrics. It enables users to apply multiple selection strategies and metrics in a single function call, visualize variable selection processes, and export results in various formats. StepReg offers a data-splitting option to address potential issues with invalid statistical inference and a randomized forward selection option to avoid overfitting. We validated StepReg's accuracy using public datasets within the SAS software environment. For an interactive web interface, users can install the companion StepRegShiny package. The methodology is described in Li et al. (2026) <doi:10.32614/RJ-2026-005>.

Covariate adjustment for randomized trials using stable balancing weights (SBW), as proposed by Irish, Zubizarreta, and Luedtke (2026) <doi:10.48550/arXiv.2609.01638>. sbw_weights() fits exact-balance SBW for a two-arm study by a closed-form solve with a nonnegative quadratic-programming fallback; sbw_estimate() computes a closed menu of treatment-effect estimands (average treatment effect, relative risk, survival ratio, Mann-Whitney, quantile contrasts) from the fitted weights, with bootstrap confidence intervals.

Recent gcc and clang compiler versions provide functionality to test for memory violations and other undefined behaviour; this is often referred to as "Address Sanitizer" (or ASAN') and "Undefined Behaviour Sanitizer" ('UBSAN'). The Writing R Extension manual describes this in some detail in Section 4.3 title "Checking Memory Access". . This feature has to be enabled in the corresponding binary, eg in R, which is somewhat involved as it also required a current compiler toolchain which is not yet widely available, or in the case of Windows, not available at all (via the common Rtools mechanism). . As an alternative, pre-built Docker containers such as the Rocker container r-devel-san or the multi-purpose container r-debug can be used. . This package then provides a means of testing the compiler setup as the known code failures provides in the sample code here should be detected correctly, whereas a default build of R will let the package pass. . The code samples are based on the examples from the Address Sanitizer Wiki at <https://github.com/google/sanitizers/wiki>.

An implementation of the surrogate approach to residuals and diagnostics for ordinal and general regression models; for details, see Liu and Zhang (2018) <doi:10.1080/01621459.2017.1292915> and Greenwell et al. (2018) <doi:10.32614/RJ-2018-004>. These residuals can be used to construct standard residual plots for model diagnostics (e.g., residual-vs-fitted value plots, residual-vs-covariate plots, Q-Q plots, etc.). The package also provides plot methods for producing standard diagnostic plots using lightweight base R graphics (via tinyplot'). The package currently supports cumulative link models from packages MASS', ordinal', rms', and VGAM', binary and other generalized linear models fit with glm', and multinomial models or general classifiers via a matrix of predicted class probabilities.
