✦ Synopsis

The results obtamed by mmmuzmg the sum of squares of dtierent functions of measured variables x, 1, y, P, wrth and wtthout weightmg are compared The unwelghted regressIon leads to different values of estimated parameters accordmg to the type of minimization cnterion It IS shown that the weighted regression of .x, t, y data gves rise to the same values of estimated parameters not dependmg on the type of mmmuzatlon cnterion Ttus IS also true for x, r, P data It LS shown that the simultaneous correlation of x, t, y, P data IS erroneous but ttus statement 1s valid only for "classical" treatment A very simple method IS proposed based on the concept of "multlresponse model" for treatment of all (x, t, y, P) data together
