Question

Which of the following statements is true?

1.For a classification tree we use "method=anova" and for a regression tree we use "method=class"
2.ANOVA means analysis of covariance
Correct!
3.ANOVA means analysis of variance
4.Trees for continuous outcomes are called classification trees, and trees for binary outcomes are called regression trees

Answer 1

Trees for continuous outcomes are called classification trees, and trees for binary outcomes are called regression trees.

Step-by-step explanation:

The statement that is TRUE is option 4: Trees for continuous outcomes are called classification trees, and trees for binary outcomes are called regression trees.

A classification tree is used when the outcome variable is categorical, while a regression tree is used when the outcome variable is continuous. The 'method=anova' and 'method=class' options mentioned in options 1 and 2 are not correct.

Analysis of Variance (ANOVA) is a statistical method used to test whether the means of three or more populations are equal. It is often used in one-way ANOVA tests to compare means across several groups.
