【Abstract】 Optimum regression equations can be obtained by the statistic either AIC or Cp, and the procedure of path analysis also leads to the attainment of the best variab1e subset, then which one is most superior to the others in the process of variable selection. This article has carried out the constructive exploration of above problem thru practical examples in this connection.更多还原
