Conditional change model

Conditional Change Model

In statistics this is the analytic procedure in which change scores are regressed on baseline values, together with the explanatory variables of interest (often including an indicator of a treatment group). The method has some substantial advantages over the usual two-sample t-test recommended in textbooks. For a more complete discussion see File:Conditionalchange.pdf.
