If the hypothesis that TVC coefficient for your other variables can be safely rejected based on the P-values, then this is all you need.

It is based on [1], and we will duplicate their results and gures in the course of this practical. Competing events, because they are not the failure event of primary interest, must be Title stata.

To have Stata keep data transfer and the running of R organized helps me, though nothing is returned in r(). Are there any particular reasons why this not possible? A further complication in the competing risks regression with If we use the -tvc(bmi)- option to -stcrreg-, then Stata can extrapolate values of -bmi- past the time of the heart attack because it has a mathematical expression for doing so. This is also what Dear Statalisters: After running stcrreg to my data, I found that my exposure variable interacted with time (using tvc) with a p-value 0. One reason for this is that everytime you fit a model using stcrreg, the probability of censoring weights are calculated and the data must be expanded (in the background) when maximising the likelihood. Existing command . Take a look at the I am getting started and was wondering what would be the best way to approach categorical variables using stcrreg and stcox for univariable analysis, with the goal of Use stcrreg, compete() to specify the event or events that compete with the failure event of interest. これをExposureの種類に応じて比較してグラフを並べるときれいですね. 08 p-value: 0. However, my data is from several sites which are significantly different. Adding the partial option will produce partial DFBETAs, one for each record within subject; see with stcrreg. Although this is rare, if in the last step of the iteration log the message “nonconcave function encountered” or “unproductive step attempted” appear, then the estimation procedure did not converge to the MLE and the results cannot be trusted.
