The residuals obtained from fitting a structural equation model are crucial ingredients in obtaining chi …-square goodness-of-fit statistics for the model. The authors present a didactic discussion of the residuals, obtaining a geometrical … interpretation by recognizing the residuals as the result of oblique projections. This sheds light on the concept of degrees of …

We propose a linear regression model with slash-elliptical errors. The slash-elliptical distribution with parameter q … estimation, hypothesis testing, generalized leverage and residuals for the proposed model. In the analysis of local influence, we …

The modified statistical tests can be used on time series of NMA residuals (the NMA residual is the familiar … material balance), or on a combination of PM and NMA residuals. The PM residuals can be generated on a fixed time schedule or …
