[R] Conditional Logistic Regression with Multilevel Data [using clogistic() in Epi and lmer() in lme4???]

[Heather H Kettrey]

I need to run some conditional logistic regression models on a multilevel matched dataset (propensity score matched data from multiple research sites).


I can pretty easily use the clogistic() function in the Epi package to run conditional logistic regression models on each separate/nested subset of the data (e.g., data obtained from each research site separately). However, I cannot figure out how to run an aggregate analysis (of all aggregated sites) in a way that accounts for clustering.


When using unconditional logistic regression I can run the aggregate analysis lmer() function in the lme4 package. However, I cannot figure out how to run conditional logistic regression with the lmer() function (I am also open to any other packages/functions that might work).


Thanks in advance for help with this.
