Additive model
Revision as of 11:44, 7 November 2023 by Editor iHTS (talk | contribs)
A model in which the combined effect of several independent factors is the sum of the isolated effects of each factor.
Note: For example, if a factor X increases a risk by a in the absence of Y, and if a second factor Y increases the risk by b in the absence of X, the combined effect of the two factors is a + b.
