NettetThe model should meet all of the assumptions of the regression model in order to be reliable. These assumptions include linearity, normality, homoscedasticity, multicollinearity, and autocorrelation. Linearity can be checked by examining the scatterplots of the predictor and dependent variables. Normality can be checked by examining the ... NettetHierarchical Regression Explanation and Assumptions. Hierarchical regression is a type of regression model in which the predictors are entered in blocks. Each block represents one step (or model). The order (or which predictor goes into which block) to enter predictors into the model is decided by the researcher, but should always be based on ...
Nettet22. apr. 2024 · Be careful: the R² on its own can’t tell you anything about causation..
