Estimate sample size based on precision rather than power. precisely is a study planning tool to calculate sample size based on precision. Power calculations are focused on whether or not an estimate will be statistically significant; calculations of precision are based on the same principles as power calculation but turn the focus to the width of the confidence interval. precisely is based on the work of Rothman and Greenland (2018).

This Ruby library provides an implementation of the Matrix
and Vector
classes. The Matrix
class represents a mathematical matrix. It provides methods for creating matrices, operating on them arithmetically and algebraically, and determining their mathematical properties (trace, rank, inverse, determinant, eigensystem, etc.). The Vector
class represents a mathematical vector, which is useful in its own right, and also constitutes a row or column of a Matrix
.
Texinfo is the official documentation format of the GNU project. It uses a single source file using explicit commands to produce a final document in any of several supported output formats, such as HTML or PDF. This package includes both the tools necessary to produce Info documents from their source and the command-line Info reader. The emphasis of the language is on expressing the content semantically, avoiding physical markup commands.
