Very basically, predictors that are excluded from the final model don't add anything to the predictors that are included in the final model when it comes to predicting some outcome variable. The final model is no different than any other multiple linear regression model. The predicted outcome is...
regressionIn experimental designs, it is usually assumed that the data follow normal distributions and the models have linear structures. In practice, experimenters may encounter different types of responses and be uncertain about model structures. If this is the case, traditional methods, such as ...
Stepwise regression (SR) was an extension of linear regression models based on Pearson's correlation coefficient. Previous results of experiments before combination showed that Ori, Que and Vit could effect the cell viability, the leakage rate of LDH and the level of NO, presenting obvious linear...
