    Is the transpose of a g inverse the g inverse of transpose of the matrix?

    While working with linear models,I came across the situation where the proof of some results might be easier if we apply that transpose of g inverse is g inverse of transpose of a matrix.In R this codes library(MASS) x1=c(1,0,1,1) x2=c(3,6,5,2) x3=c(2,4,6,1) x4=c(3,5,2,1)...
