When two predictors do not interact, we say that each predictor has an " additive effect " on the response. More formally, a regression model contains additive effects if the response function …

This plot can suggest simpler transformations of predictor variables than use of the full-blown smoothing spline: here maybe a quadratic? The band shows a pronounced deviation from …

plotLocalEffects(Mdl,queryPoint) creates a bar graph showing the local effects of the terms in the generalized additive model Mdl on the prediction at the specified query point queryPoint.

There are two ways to include interactions between variables: When x2 is a factor, the factor needs to be added as a main effect in the model. We will examine interaction effects to …

18 Plotting an Additive Plot Here we describe how one displays an additive fit. This graphical display may look a bit odd at first, but it is an effective way of portraying the additive fit found …

Jan 23, 2015 · First we will draw each model separately, illustrating two different coding strategies for layering points and lines. Then we will combine these strategies in the final graph. With …

Download scientific diagram | Manhattan plot of the additive effects obtained using the three kinship structures (in order from top to bottom) Van Raden (V), Meuwissen (M), and Yang (Y),...

A regression model contains interaction effects if the response function is not additive and cannot be written as a sum of functions of the predictor variables.

In contrast, the figure below shows drugs that act synergistically. The curves are fit assuming the two drugs act in an "additive" or "independent" manner, and these curves don't fit the data …

a scatter plot with predicted on the x-axis and residual on the y-axis gives a resid-ual vs. t plot, while a quantile-normal plot of the residual column allows you to check the Normality assumption.
