|Subject: ||cross validation - optimal number of samples|
I'm considering using a cross-validation technique for a multivariate
logistic regression model. Is there a formula for determining the optimal
number of subsamples into which I should divide my sample?
I'm curious if it would be appropriate to use a variation of the optimal
allocation formula used to calculate optimal stratum sizes that minimize
the variance of some variable of interest X in stratified sampling plans.
