Informative Hypotheses


Restriktor (Vanbrabant, 2017) allows for easy-to-use testing of linear equality and inequality restrictions about parameters and effects, in linear, robust linear and generalized linear statistical models.

For model selection under (in)equality constraints, restriktor allows to compute the Generalized Order-Restricted Information Criterion (GORIC) by means of the goric() function.
