The true relationship between temperature and sales remained however. Correlated data can frequently lead to simple and multiple linear regression giving different results. The multiple regression with three predictor variables (x) predicting variable y is expressed as the following equation: y = z0 + z1*x1 + z2*x2 + z3*x3 The “z” values represent the regression weights and are the beta coefficients.
