For model diagnostics … WebJul 15, 2011 · Take a look at the data, plot (archlogfl~co2,type="b") library (nlme) g0 <- gls (archlogfl~co2) plot (ACF (g0),alpha=0.05) This is an autocorrelation function of the residuals, with 95% confidence intervals (note that these are curvewise confidence intervals, so we would expect about 1/20 points to fall outside these boundaries in any case).

WebR functions such as gls () will compute the regression variance (if I knew how gls () does this, it would answer my question). However I cannot use gls () in this case since I am specifying a user-defined covariance (weighting) matrix, and gls () only accepts a limited set of specific correlation structures.
