Greetings, I'm using MSM (mutli-state markov modeling) package to study the progression of fibrosis in U.S hepatitis C population. I find this is a very fascinating tool for an applied researcher like myself. I have a four stage progression only model without any absorbing stage, also assuming no misclassification error in the data for the time being. I also have a couple covariates in the model. so I get these three transition rates. and I was wondering how I can compare these transition rates to be able to say that they are not equal statistically. (I guess I might be thinking too hard on this, can I just use qratio.msm function and examine confidence intervals..?) but I would very much appreciate any advice, kind regards, kelly ++++++++++++++++++++++++++++++++++++ KyungAh (Kelly) Im, M.S/PhD student.
