Example 1: The multiple linear regression equation is as follows:, where is the predicted or expected value of the dependent variable, X 1 through X p are p distinct independent or predictor variables, b 0 is the value of Y when all of the independent variables (X 1 through X p) are equal to zero, and b 1 through b p are the estimated regression coefficients. b = regress(y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X . towardsdatascience.com Multiple Linear Regression: It’s a form of linear regression that is used when there are two or more predictors. We w i ll see how multiple input variables together influence the output variable, while also learning how the calculations differ from that of Simple LR model.
