Breakpoints for multiple variables using Segmented
...lationships with the response?. However, the syntax for
including multiple ?Z? and ?psi? (?starting values for the break-point(s)?)
is not stated. Does anyone have any suggestions?
Here is an example of correct code for detecting single breakpoint:
model.seg<-segmented.glm(obj = model.glm, Z = predictor_variable, psi = 2 ,
it.max = 50)
Thanks very much for your help.
