(Back ON-LIST). (And combining two of Marc's posts). > Perhaps I am missing something here, but with clogit(), or Heather's initial attempt at using clogistic(), as both have 'strata' arguments, wouldn't the 'strata' argument need to be able to accept a nested structure, along the lines of strata(

Re: [R] Sample size required to estimate population variance

Thanks for the suggestion but I'm not sure that it answers my original question.I need to know how many samples I need to collect to collect in order to estimate the sample size needed to achieve a specific margin of error for confidence intervals for the population variance. I'm not sure wheth
