Crisis of confidence averted: Impairment of exercise economy

Transform the dependent variable. I always save transforming the data for the last resort because it involves the most manipulation. Remember that there are two sources of variance in this model, the residual observation level variance, and that pertaining to person. Combined they provide the total residual variance that we aren’t already capturing with our covariates. In this case, it’s about 0.12, the value displayed on our diagonal.

This can lead to difficulties in the interpretation of the raw residuals, yet it is still used. The formula for the raw residual is Analysis of Variance Identity The total variability of the observed data (i.e., the total sum of squares, SS T) can be written using the portion of the variability explained by the model, SS R, and the portion unexplained by the model, SS E, as: The above equation is referred to as the analysis of variance identity.

Smaller residuals indicate that the regression line fits the data better, i.e. the actual data points fall close to the regression line.

Robust residual control chart for contaminated time series

Consider the following linear Identity involving norms of tted values and residuals Before we continue, we will need a simple identity that is often useful. In general, if a and b are orthogonal, then ka + bk2 = kak2 + kbk2. If a and b a are orthogonal, then kbk2 = kb a + ak2 = kb ak2 + kak2: Thus in this setting we have kbk2 k ak2 = kb ak2. Cross-validated residuals in PLS and least squares regression are conceptually similar, but their calculations differ. Formula In PLS, the cross-validated residuals are the differences between the actual responses and the cross-validated fitted values.
