You are building a classification tree for a binary outcome (Class A and Class B). A node currently contains 10 observations: 8 from Class A and 2 from Class B. Calculate the Gini Impurity of this node.(Hint: G i n i = 1 − ∑ k = 1 K p k 2 {“version”:”1.1″,”math”:”Gini = 1 – \sum_{k=1}^{K} p_k^2″} , where pk is the proportion of class k. Please provide all your answer as a two-digit decimal (e.g., 0.73.).

You have a dataset with 100 predictors, but you suspect only 10 are truly relevant. Which method would be more appropriate?

In Generalized Additive Models (GAMs), the model takes the form: Y = \beta_0 + f_1(x_1) + f_2(x_2) + … + f_p(x_p) + \epsilon. What does this allow?

In Principal Components Regression (PCR), the principal components are constructed using only the predictor variables without considering the response variable (y), which means some components with high variance may not be relevant for predicting the response.
