Now showing the factor itself in the output, not just rows for coefficients for levels of the factor.
When a factor is included in a model, the summary output will show the name of the factor and show the p-value for the factor (based on Type-III sums of squares). This p-value is not affected by further use of the factor (i.e. in an interaction). Sometimes this p-value cannot be calculated (i.e. when there are unobserved factor level combinations) and the p-value will be omitted.
The baseline level of a factor is now shown, with an estimate of 0.
All p-value output for levels of a factor is indented to the right by two characters to distinguish it from being a level.
The output for each factor level is now just the level name and not the name of the variable concatenated with the level name. The level name is also indented by two characters, again to distinguish it from the variable itself.
Removing F-statistic and associated p-value as it's mostly useless. It only shows us whether nothing is correlated with the response variable, i.e. whether we're completely wasting our time.
Added a new
plot.lm function. The main difference being that
it includes bootstrapped smoothers in its output as well as the
regular trend lines. Also includes plots based on the
Added partial residual plots. Most useful for determining whether the inclusion of a transformation of a variable is necessary. For example, adding a logged or polynomial explanatory variable to the model.
