Dear Detlew,

❝ […] the entry suggest for me that the TIE (with values >0.05) is significant <0.05. Maybe it's my misunderstanding. To avoid this many statisticians state "significant at alpha=0.05". But then the Hypotheses have to be given else.

I see!

Change lines 17 and 32 from

res  <- cbind(CVs, n=NA, forced=FALSE, GMR=NA, TIE=NA,

              signif=" n. s.", stringsAsFactors=FALSE)

  if (res[j, "TIE"] > bt.sig) res[j, "signif"] <- "p<0.05"

res  <- cbind(CVs, n=NA, forced=FALSE, GMR=NA, TIE=NA,

              "signif >0.05"="n. s.", stringsAsFactors=FALSE)

  if (res[j, "TIE"] > bt.sig)

    res[j, "signif >0.05"] <- "at alpha=0.05"

Will give

swT/swR: 2 

   CVwT   CVwR   n      GMR      TIE  signif >0.05

 0.0600 0.0300 430 1.032106 0.050580 at alpha=0.05

 0.0801 0.0400 156 1.043027 0.048675         n. s.
