Multiple Regression: Predicting CDRS Scores
Not what you're looking for?
See the attached file.
Examine the multiple regression results in the attached document. Determine whether RADS significantly predicts CDRS scores after adjusting for the effects of the other predictors in the model. Determine whether AGE significantly predicts CDRS scores after adjusting for the effects of the other predictors in the model. State the statistical results that support your conclusions and provide the regression equation that could be used for prediction purposes.
Assumptions
- Assume RADS is an X (predictor or independent) variable
- Assume AGE is an X (predictor or independent) variable
- Assume CDRS is the Y (response or dependent) variable.
- Assume the level of significance for all statistical tests is p = 0.05
- Assume the research hypotheses are non-directional.
