❓ What is the Least Squares Method in Multiple Linear Regression?
The least squares method estimates regression parameters by minimizing the sum of squared differences between actual and predicted values.
❓ Why use matrix algebra in regression?
Matrix algebra simplifies computations, especially when dealing with multiple independent variables, making the estimation process efficient and scalable.
