Interpretation interaction term
WebThe hypothesized population equation to model interaction is: Eq. 3.2.8: E(Y) = B 0 + B 1 X 1 + B 2 X 2 + B 3 X 1 X 2; The cross-product term, X 1 X 2, is the interaction term, so B 3 in Equation 3.2.8 is the slope of interest for testing interaction. To model interaction with sample data, we multiple the two independent variables to make a new ... WebNov 16, 2024 · Interpretation of coefficient for interaction term in regression.

WebIn statistics, an interaction may arise when considering the relationship among three or more variables, and describes a situation in which the effect of one causal variable on an outcome depends on the state of a second causal variable (that is, when effects of the two causes are not additive). Although commonly thought of in terms of causal relationships, … WebThe term XZ is the interaction of the predictor with the moderator. Y = b0 + b1X + b2Z + b3XZ. We will illustrate the simple slopes process using the hsbdemo dataset that has a statistically significant continuous by continuous interaction. As shown in the code below that read is the response variable, math is the predictor and socst is the ...
