Re: Empirical data Fitting

Is there a definite need for fitting the distribution? If you have to try many distributions or fit many parameters, the mean squared errors of the resulting distribution estimates are no lower than that of nonparametric estimates (empirical CDF or kernel density estimator). Frank Harrell On

Re: Cross validation procedures

. The bootstrap is easy to program and can correctly penalize for model uncertainty caused by variable selection (unlike cross-val). Frank Harrell -- Frank E Harrell Jr Prof. of Biostatistics Statistics Div. of Biostatistics Epidem. Dept. of Health Evaluation Sciences U. Virginia

Re: Statistics Q

-Cox, where the transformation parameter lambda is explicitly a part of the variance-covariance matrix will be ok. Whenever a multi-step strategy is used there should be a multi-step simulation to verify that statistical properties such as confidence coverage are preserved. Frank Harrell -- Frank E
