Moderation ( Interaction) Analysis Using Linear Regression ...

NettetWe will consider a regression model which includes a continuous by continuous interaction of a predictor variable with a moderator variable. In the formula, Y is the response variable, X the predictor (independent) variable with Z being the moderator variable. The term XZ is the interaction of the predictor with the moderator. Y = b0 + … NettetIn multiple linear regression, we can use an interaction term when the relationship between two variables is moderated by a third variable. This allows the slope coefficient for one variable to vary depending on the value of the other variable. For example, this scatter plot shows happiness level on the y-axis against stress level on the x-axis. harvey norman carpets near me

NettetIn a linear model that contains only linear terms, i.e. no quadratic, log, and other kinds of nonlinear terms, the main effect of each regression variable is the same as its partial effect. For all other models, the main effect of variable can be calculated by averaging the partial effect of the variable over the entire data set.
