Re: [R] Can I increase the size of an asterisk in plotmath()?

Hi Rolf, A bit of poking around reveals that different fonts have different size asterisks. If you are not already using Times Roman, it might be worth a look. I only have Windows on this (work) PC, so I can't check the Postscript fonts. Jim On Fri, Jul 1, 2016 at 12:50 PM, Rolf Turner

Hi Carlos, The STATA function assumes estimated population SDs. If you have sample SDs you can specify with this: combine<-function(n,mu,sd,sd.type=c("pop","sample")) { N<-sum(n) mean<-sum(n*mu)/N if(sd.type[1]=="sample") { meanss<-(n[1]*(mean-mu[1])^2+n[2]*(mean-mu[2])^2)/N
