⚠️There's a newer version (1.3-4) of this package.Take me there.

SNSequate (version 1.0)

Standard and Nonstandard Statistical Models and Methods for Test Equating

Description

The package contains functions to perform various models and methods for test equating. It currently implements the Kernel Method of Equating using the (traditional) Gaussian kernel and also nonstandard alternative kernels such as the logistic and uniform. More kernels will be implemented in the near future as well as other nonstandard methods of equating.
