What is the basic definition of linear regression?
A method that functions to predict the influence of two or more specific functional variables.
A statistical method that tests the extent of the causal relationship between the independent variable (X) and the dependent variable (Y).
A statistical method that involves more than one independent variable or predictor against one dependent variable.
A statistical technique used to develop a model that can predict the value of a dependent variable (Y) based on the value of an independent variable (X)
