06 / 255 We will first use the log of ‘Salary’ as the response and the ‘Years’ and ‘Hits’ as the two predictors. Background Examining residuals is a crucial step in statistical analysis to identify the discrepancies between models and data, and assess the overall model goodness-of-fit.

In R, a family specifies the variance and link functions which are used in the model fit.

The residual sum of squares is 4777, which gives an R2 of ~35% (1-4777/7405), which is.

. The trick allows us to propose, among others, an adapted form of the Likelihood Ratio deviance statistic with which we can test statis-tically the signiﬁcance. .

.

Decision Trees. To make a prediction for a new observation, we typically use the mean (for continuous response. .

Distribution of residuals: Min. 5 Advertising < 13.

.

The expected number of events is the number of events predicted by the survival model. The formula is.

. Because these only rely on the mean structure (not the variance), the residuals for the quasipoisson and poisson have the same form. If it is a continuous response it’s called a regression tree, if it is categorical, it’s called a classification tree.
