Objectives

• To create and test a Linear Regression Machine Learning Model.
• Specifying models using formula strings and DataFrames
• To estimate parameters of linear regression model by minimizing sum of squared residuals using statistical OLS method.

OLS Linear Regression ML Model

OLS Regression Model General Formula

Predicted Value = β₀ + β₁·x₁ + β₂·x₂ + ... + βₚ·xₚ + ϵ

Where:

• β₀ = intercept
• β₁, β₂, ..., βₚ = regression coefficients
• x₁, x₂, ..., xₚ = input features (independent variables)
• ϵ = error term (residual)
