Abstract
A year ago, a paper dealing with parameters' errors of a least-squares determined curve was published by Cecchi. Very recently, Kalantar cor rectly pointed out that the results quoted by Cecchi for the variance estimates of a straight-line fit do not agree with those previously re ported by other authors. Nevertheless, for straight-line fits the form alism discussed by Cecchi is essentially correct. In the present commu nication, complete agreement between results is achieved after some de tailed calculations.
