I am a new user of R for Windows, enthusiast about the many functions of the Design and Hmisc libraries. I combined the results of a Cox regression model after multiple imputation (of missing values in some covariates). Now I got my vector of coefficients (and of standard errors). My question is: How could I use directly that vector to run programs such as 'nomogram', 'calibrate', 'validate.cph' which, in contrast, call for the saved results form 'cph' ? I did not use 'aregImpute' for multiple imputation. However, even if I did it, 'fit.mult.impute' seems not to allow specifying the option 'surv=TRUE' (essential to get a nomogram) or 'x=TRUE, y=TRUE' (which are essential for 'calibrate' and 'validate.cph'. Therefore, I dont't see how I could get a nomogram or run other Design functions after 'aregImpute'.
thank you so much in advance Umberto
