Dear Helmut,

❝ Below the intra-subject residuals to 5 decimals and the

❝ R-code:

❝ intra <-

❝ c(-1.12602,+1.31764,+0.17871,+1.04384,-1.44654,-0.85471,-0.45394,

❝ -1.09608,+0.32237,+0.41330,+1.68203,-1.27489,+0.84339,+0.45090)

Here are mine: intra-indiv. residuals / studentized residuals

Red: different in sign to yours.
Mine are identical to Yung-jin (see above).
