Richard, Thanks, Have not previously used the HH package, but looks as if it contains many useful tools. Will check out your book also. Best regards, James On Thu, Dec 1, 2016 at 10:18 PM, Richard M. Heiberger wrote: > James, > > Please look at the maiz example, the last example in ?MMC > help

James, Please look at the maiz example, the last example in ?MMC help("MMC", package="HH") where I show how to construct and calculate a set of orthogonal contrasts for a factor in an analysis of variance setting. mmc and mmcplot use glht in the multcomp package for the underlying calculations.

[R] confidence intervals for orthogonal contrasts

2016-12-01 Thread James Henson
Hi R users, Is there a way to calculate a confidence interval for each contrast in a set of orthogonal contrasts? The ‘multcomp’ package will calculate a CIs at the 95% family-wise confidence level. But, these confidence intervals are extremely wide. Thanks for your help. Best regards, James ___
