A: The Normal Equation can handle multicollinearity by using a regularization parameter to prevent the coefficients from growing too large. This helps to stabilize the solution and prevent overfitting.
In simple terms, the Normal Equation is a mathematical formula that calculates the optimal coefficients for a linear regression model. Given a dataset, the equation takes into account the feature matrix, the target variable, and a regularization parameter to find the best-fit line that minimizes the sum of squared errors. The equation is as follows: θ = (X^T X)^-1 X^T y, where θ represents the coefficients, X is the feature matrix, y is the target variable, and (X^T X)^-1 is the inverse of the transpose of the feature matrix multiplied by itself.
