Multiple linear regression (MLR), also known simply as multiple regression, is a statistical technique that uses several explanatory variables to predict the outcome of a response variable.

2000-05-30 · The general form of the multiple regression equation is The variables in the equation are (the variable being predicted) and x 1 , x 2 , , x n (the predictor variables in the equations). The "n" in x n indicates that the number of predictors included is up to the researcher conducting the study. normal equations can still be solved, but the solution may not be unique. The inverse of X�X exists, if the columns of X are linearly independent.
