Hello After (simple random cluster) resampling with replacement I ran MSM function and I'm getting the following warning message ,which I'm not sure why. I don't have any absorbing stage set up in my MSM model. I have a 4 stage uni-directional MSM model. The only thing I see might be a problem is that when the last stage (stage 4 in my data) gets repeated it seems to give me a warning message. although, it picks only one observation whereas there might be other such cases in the data (printing only the first case?)
> out1.msm2 <-msm(stage~years,subject=patient,data=mydata2,qmatrix=new.twoway9.q,con trol=list(trace=1,report=1),covariates=~black+tport11,constraint=list(bl ack=c(1,1,1),tport11=c(1,1,1))) ... Warning message: Absorbing - absorbing transition at observation 30 in: msm.check.model(msmdata$fromstate, msmdata$tostate, msmdata$obs, My data at observation around 30 look like ('years' is the time variable) > mydata2[27:35,] count patient black years stage tport11 pcount 1 1029 1 0 1 1 17 1 1029 1 0 1 1 17 2 1029 1 19 4 1 17 2 1029 1 19 4 1 17 1 1033 0 0 1 1 20 1 1033 0 0 1 1 20 2 1033 0 18 4 1 20 2 1033 0 18 4 1 20 I'm wondering if I can ignore this warning message or should I have not done resampling with replacement. Any input would be greatly appreciated.
