Define an omnibus secondary model

omnibus_secondary() defines a secondary model specification that can be used inside fit_omnibus(), fit_omnibus_growth(), or fit_omnibus_inactivation(). It allows a primary-model parameter to be described by another parameterised model already available in predmicror.

Usage

omnibus_secondary(model, x, transform = c("identity", "square"))

Arguments

model

Character string naming a registered predmicror model, for example "CMTI", "CMAW", "CMPH", or "CMInh".

x

Character string naming the covariate column used by the secondary model.

transform

Character string. One of "identity" or "square".

Value

An omnibus_secondary specification.
