\title{Marginal paired two sample test}
\usage{paired.marginal(data, model, robust, alternative, psi0, equalvar)}
\description{The robust version uses the Wilcoxon signed rank test, otherwise a paired t-test will be performed.}
\details{A vector of classlabels needs to be provided to distinguish the two paired groups. The arrangement of group indices does not matter, as long
		as the columns are arranged in the same corresponding order between groups. For example, if group 1 is code as 0 and group 2 is 
		coded as 1, for 3 pairs of data, it does not matter if the classlabel is coded as (0,0,0,1,1,1) or (1,1,1,0,0,0) or (0,1,0,1,0,1)
		or (1,0,1,0,1,0), the paired differences between groups will be calculated as group2 - group1.}
