A set of distributions which can be used for modelling the response variables in Generalized Additive Models for Location Scale and Shape, Rigby and Stasinopoulos (2005), <doi:10.1111/j.1467-9876.2005.00510.x>. The distributions can be continuous, discrete or mixed distributions. Extra distributions can be created, by transforming, any continuous distribution defined on the real line, to a distribution defined on ranges 0 to infinity or 0 to 1, by using a "log" or a "logit" transformation respectively.
Various R programming tools for data manipulation, including: - medical unit conversions, - combining objects, - character vector operations, - factor manipulation, - obtaining information about R objects, - manipulating MS-Excel formatted files, - generating fixed-width format files, - extricating components of date & time objects, - operations on columns of data frames, - matrix operations, - operations on vectors, - operations on data frames, - value of last evaluated expression, and - wrapper for 'sample' that ensures consistent behavior for both scalar and vector arguments.
Useful tools for writing vector graphics devices.
Generalized Estimation Equation solver.
Generalized estimating equations solver for parameters in mean, scale, and correlation structures, through mean link, scale link, and correlation link. Can also handle clustered categorical responses.
