A

Ordinary Least Squares

B

Maximum Likelihood Estimation

C

Ridge Regression

D

Bayesian Estimation

Understanding the Answer

Let's break down why this is correct

Maximum Likelihood Estimation, or MLE, looks for the parameter values that make the observed data most probable. Other options are incorrect because Ordinary Least Squares assumes a continuous outcome and normal errors, which is not true for 0/1 data; Ridge Regression adds a penalty to shrink coefficients, helping with overfitting, but it does not directly maximize the probability of the observed outcomes.

Definition

Parametrized predictors are predictive models that are defined by a set of parameters, such as vectors or matrices. Examples include linear regression models for scalar and vector outputs. The parameters determine the structure and behavior of the predictor.
