The simplest case is that of linear regression, in which the regression equation of y on x is written as y = a + bx. The parameters, a and b, are called regression coefficients. Correlation. This indicates the nature and strength of the relationship between two variables.

Choose a significance level (P-value) to enter the model (SLE) and a significance level to stay in the model (SLS). Some computer packages require that SLE < SLS. Fit all k simple regression models, choose the independent variable with the largest t-statistic (smallest P-value).
