Consider the iris data in the library datasets 1)Fit a manova model ( Y=BX + E) with E Np,n(O, , I) and Y each measurement (sepal length, sepal width, petal length,petal width) 2)Calculate the maximum likelihood estimators for B using the formula B=YX' [ (XX')^1]. The result is a matrix,not a number. X is an identity matrix.X' is the transpose of X.
