Quizplus · Accepted Answer

The reliability/unreliability of a multiple regression depends on both internal and external validity. Internal validity is related to whether the model accurately reflects the relationship between the predictor(s) and the outcome variable, while external validity is related to whether the model can be generalized to other populations or contexts. The quality of statistical software may affect the accuracy of the results, but it is not the primary factor determining reliability.
