Gw mau tau How to Studentize dari Studentized residual. Jelasin dalam bahasa sunda

For this simple modél, the "design matrix" is

and the "hat matrix" H is the matrix of the orthogonal projection onto the column space of the design matrix:

The "leverage" hii is the ith diagonal entry in the hat matrix.  The variance of the ith residual is

The corresponding Studentized residual is then

where  is an appropriate estimate of σ.
