a bit slicker if %*% worked with multidimensional arrays multiplying
them so that if the first arg is a multidimensional array it is mulitplied
along the last dimension (and first dimension for the second arg).
Then one could have written:
Tbar <- tarray %*% t(wt) / rep(wti, each = 9)
which is a bit
