| Abstract: | Cp statistic, a criteria used to select the "best" regression equation, has gained popularity in recent years. This paper gives a BASIC program evaluting all possible subsets regression and a special attention is paid to the fact that the BASIC language has less memory space. An example is also given to describe the procedure with the help of the Mallows Cp statistic to select a regression equation. |
