interaction

Attached you will find a well known research paper. If you go to page 438 (page 9 of the pdf file) you will find a model where: change in tax rate = b1xMiss + b2x Miss Amount +b3(Miss x Miss Amount) + controls according to the model , firms play with their accounts in order to pay less...

Hello friends, I've used a negative binomial GLM to look at how invertebrate abundance (over dispersed) is affected by seagrass density. There is a negative interaction between seagrass density and epiphyte biomass (the little plants growing on seagrass blades that invertebrates eat)...

Hello, I have found significant interaction effects when analyzing a negative binomial generalized linear regression model. However, I am not sure how to further explore the interaction. I am currently using SPSS. How can I conduct follow-up simple effects to examine the interactions? Can I...

Hey everyone. This is my first post here so please be kind to me :) . For my thesis my aim is to run a moderation analysis between organizational commitment and training. My dependent variable is job satisfaction. Org.commitment comes from 4 5-point likert-items, therefore I calculated the...

Hello, I'm relatively new to R and have run into some problems. Hoping someone can help! I'm using lme on a model with several, both within/between, categorical/continuous and fixed/random effects. I have 1 x fixed 2-level categorical between-subjects variable "group" (dose vs. placebo), 1...

We performed a multiple linear regression with valence (negative, positive and neutral) as independent variable, social curiosity as controll variable and recognition performance as our dependent variable. No we got this graph (see attachments). Do we have a main effect and interaction...

I was given data to work on for a lab report. I did a 2 x 2 between subjects ANOVA (if it matters n=187). Main effect of IV1 was not significant. Main effect of IV2 was not significant. Interaction was not significant (although was .62 which I'm supposed to report as "marginally...

Hey people, I am trying to find an appropriate mediation analysis method. I want to investigate how an INTERACTION of two variables mediates the association of two different variables. I have read about mediation analysis with one or multiple mediators, but nothing about an interaction as the...

Hi, I am stuggling to find the right words for the statistical terms I would like to look up. Hope, you can help :-) I am looking at a higher order construct (organizational climate), which manifests in eight dimensions. I am interested in elaborating how these dimensions interact and what...

Hi everyone, I have got a question regarding the specification of interaction effects in panel regressions (fixed effects within estimators). I would like to know: Can I create an interaction-term between a time-varying and a time-invariant variable? Some background: My data is from...

I have run a forum search and an internet search, and tried posting this question on other forums, but have been unable to find an answer to my specific problem. My question concerns interpretation of simple slopes generated from moderation analysis. I have conducted a moderation analysis as...

I am trying to check if the relationship between X and Y is a moderated by M. Model is: Y = X + XX + M + XM + XXM X - independable, M - moderator, Y - dependable. Variables are continuous and normal. First I multiply, then center the variables (I hope it is right). Then run reggresion...

Hello! Thank you for reading and a big thank you if you can help. My goal is to successfully run this type of model in R. I know how to set up the dataset and interpret the results using HLM (the program) but I am completely lost when trying to get it into R. Screenshot of the model is...

i am using a fixed effects model with log of wage as the dependent variable when i try xi: xtreg logwage i.d08##c.yrschool exp2 married, i(id) fe where i.d08##c.yrschool is an interaction term with d08 being a dummy for the year 2008 and yrschool being a continuous variable for years of...

I have to run this regression: Y (t) = a + b1 X (t-1) + b2 Y (t-1) + b3 X (t-1)*Y (t-1) Y at time "t" is regressed using as IVs X at time t-1, Y at time t-1 (lagged dependent variable) and the Interaction of X at t-1 and Y at t-1. Both X and Y are continuous variables. I need to center...

Hi Experts, I have conducted a 2 (time: before, after) x 3 (condition 1 2 3) mixed ANOVA. The within X between interaction is only marginally significant .06. However, simple effects indicate significant change in conditions 1 and 2. The interaction indicates if change over time is a...

I am performing a "dry run" statistical analysis on my dissertation data pretest, and I'm looking for a little guidance regarding the specific analyses I need to perform. I have three primary variables: Environment. Categorical, 1 of 3 conditions. Independent, assigned by experimenter...

I'm wondering about this, and I can't find an answer anywhere. My textbook (Agresti and Finlay 2009) clearly says how to do backwards elimination on a linear model, but I'm sitting in a situation my textbook doesn't explain. Neither was I able to find anything on Google or this forum, about this...

I am new to this site, but have high hopes that I can find some relief. I have a question regarding entering interaction terms (moderation) in SPSS. Is there a conceptual difference between entering interaction terms and main effects via direct entry (at the same time) vs hierarchically (in...
