When we did multiple linear regression we looked at the relationship between shorts and sales while holding temperature constant and the relationship vanished. 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.
