Fixed 'maxiter' in the help file. Thanks. Please give the original source of that dataset. That dataset is a tiny sample of GUSTO-I and not large enough to fit this model very reliably. A nomogram using the full dataset (not publicly available to my knowledge) is already available in http://bio

Re: [R] Help understanding why glm and lrm.fit runs with my data, but lrm does not

With lrm.fit you are fitting a completely different model. One of the things lrm does, is preparing the input for lrm.fit which in this case means that dummy variables are generated for categorical variables such as 'KILLIP'. The error message means that model did not converge after the maxi

Dear all, I am using the publically available GustoW dataset. The exact version I am using is available here: https://drive.google.com/open?id=0B4oZ2TQA0PAoUm85UzBFNjZ0Ulk I would like to produce a nomogram for 5 covariates - AGE, HYP, KILLIP, HRT and ANT. I have successfully fitted a logist
