Logistic Regression: Interaction Terms
www.cantab.netInteractions in Logistic Regression I For linear regression, with predictors X 1 and X 2 we saw that an interaction model is a model where the interpretation of the effect of X 1 depends on the value of X 2 and vice versa. I Exactly the same is true for logistic regression. I The simplest interaction models includes a predictor variable formed by multiplying two ordinary predictors:

economics.harvard.eduThe interaction terms X black is a binary variable which is 1 if observation is black and 0 otherwise. X exp indicates experience. If we believe that the effect of experience on wage also depends on individual’s race, we can add the interaction term of the two. If …
Mediating vs. Moderating Variables
academic.csuohio.eduvariance (ANOVA) terms, a basic moderator effect can be represented as an interaction between a focal independent variable and a factor that specifies the appropriate conditions for its operation" (Baron & Kenny, 1986, p. 1174). Practically, this means that X2 makes a difference in terms of how and when X1 has an impact on Y.

Lecture 27 Two-Way ANOVA: Interaction
www.stat.purdue.eduSimple vs. Complex Interactions • An interaction is considered simple if we can discuss trends for the main effect of one factor for each level of the other factor, and if the general trend is the same. • An interaction is complex if it is difficult to discuss anything about the main effects. In this situation, one can only look at
Simple Effects, Simple Contrasts, and Main Effect Contrasts
web.pdx.eduFollowing a significant interaction, follow-up tests are usually needed to explore the exact nature of the interaction. Simple effects (sometimes called simple main effects ) are differences among particular cell means
DOSE-EFFECT RELATIONSHIP
www.chem.uwec.eduThe interaction of a drug with a receptor can produce a range of different types of effects. The types of interactions that can occur are shown graphically below. Drugs that bind to a receptor and mimic the effect of the endogenous ligand are called agonists. If a drug produces less than a full effect even at doses that saturate the
Lecture 34 Fixed vs Random Effects - Purdue University
www.stat.purdue.eduFixed vs. Random Effects (2) • For a random effect, we are interested in whether that factor has a significant effect in explaining the response, but only in a general way. • If we have both fixed and random effects, we call it a “mixed effects model”. • To include random effects in SAS, either use the MIXED procedure, or use the GLM
Van der Waals interaction (also known as London …
www.bio.brandeis.eduVan der Waals interaction (also known as London dispersion energies) Van der Waals (VDW) interactions are probably the most basic type of interaction imaginable. Any two molecules experience Van der Waals interactions. Even macroscopic surfaces experience VDW interactions, but more of this later.

The finding that a reduction in regional public transportation services (the exposure) affects individuals with little or no access to a car much more than those individuals with access to a car. In this example, having access to a car is the effect measure modifier. Figure 1 Risk Ra-tio Exam-ple
