Multiple regression is widely used for the analysis of nonexperimental data by investigators in social work and social welfare. Most published studies test additive models in which the effects of each independent variable on the dependent variable are assumed to be constant across all levels of ...

An interaction effect occurs when the effect of one variable depends on the value of another variable. Interaction effects are common in regression models, ANOVA, and designed experiments. In this post, I explain interaction effects, the interaction effect test, how to interpret interaction models, ...

Centering is therefore an important step when testing interaction effects in multiple regression to obtain a meaningful interpretation of results. Centering the variables places the intercept at the means of all the variables 展开 被引量: 115
Plot interaction effects. figure plotInteraction(mdl,'Sex','Weight') This plot displays the impact of a change in one factor given the other factor is fixed at a value. Be cautious while interpreting the interaction effects. When there is not enough data on all factor combinations or the dat...
Moderated multiple regression (MMR) is frequently employed to analyse interaction effects between continuous predictor variables. The procedure of mean centring is commonly recommended to mitigate the potential threat of multicollinearity between predictor variables and the constructed cross-product term. Also...
The model achieved impressive performance with AUCs of 0.962 in the cross-validation set and 0.939 in the independent test set. By incorporating interaction effects and multimodal data in our model, we observed significant accuracy improvements of 4.76% and 4.29%, respectively. Moreover, our model ...
