How to formulate an (effect-modifying) interaction with matching variable in a conditional logistic regression?
...,ptd,ht,ui)
library(survival)
# model with all covariates
mult.cl<-clogit(low~lwt+race+smoke+ptd+ht+ui+strata(pair),data=dataset)
summary(mult.cl)
# H&L drop race
mult2.cl<-update(mult.cl,.~.-race)
summary(mult2.cl)

multi1.cl<-update(mult2.cl,.~.+age:lwt)

# then comes the interaction with smoke
# no good! Here's the problem

# has to define my own variable?
