Interactions between explanatory variables

What does GLM stand for in the context of the learning material?

• General Learning Model

• General Linear Model

• General Logistic Model

• General Language Model

According to the learning material, why is R-squared not considered a basis for model selection?

• It always increases with more variables

• It is not related to the goodness of fit

• It cannot be calculated for GLMs

• It is only applicable for linear models

What is mentioned as an important concept to understand in relation to explanatory variables?

• Summation of variables

• Interactions between explanatory variables

• Independence of explanatory variables

• Elimination of explanatory variables

What does the t-statistic in a two-sample T-test tell you?

• The t-statistic indicates the probability that the two samples come from the same distribution.

• The t-statistic tells you how many standard errors the difference between the two means is from zero.

• The t-statistic provides the exact value of the means of the two samples.

• The t-statistic determines the variance within each of the samples.
