Marginal effect of beta at different values with corresponding confidence intervals

Basically I have a mixed-effect model with 2 predictors, an interaction term and a random effect that looks like this: x1<-abs(rnorm(300)) #continuous variable x2<-sample(c(1,2,3), 300, replace = T) #discrete variable x3<-sample(c("A","B","C"),…

Is there any R function that visualize the interaction effect of IV regression?

I'm looking for a function for interaction effects visualization which has a correspondence with ivreg or plm. My model is 2sls with fixed effects but it seems there are no packages available for calculating interaction effects in R. I'd be pleased…

Calculating marginal effect in Generalized Additive Model

I'd used GAM to address spatial auto correlation and considered a smooth function only for location. I would like to know how I can calculate marginal effect of the smooth term

How does "margins" calculate marginal effects in linear models?

I have a linear model (lm object) and use margins to calculate marginal effects of the regressors. As far as I understand, this is equivalent to the partial effect, if the regressor is only once in the model. That's true for "kids".…

Single marginal effect for each variable in ordered probit/logit model in R

I have to recreate a model that was build in Stata using R. I want to calculate marginal effects after using a ordered probit/logit model. I have a dependent (ordinal) variable with 5 outcomes and several independent variables. I tried "MASS" and…

OLS in R with Marginal Effects

I am looking for a code to estimate the following equation as OLS with panal data: ∆Yjt = α∆Xjt + τt + ujt where ∆ is the change of Y and X over time, j a sector, t the time, τ a set of time dummies and u the error term. I'm a beginner in R…

Marginal effect plot not corresponding to incidence rate ratio in R

Im trying to plot the marginal effect of a specific variable in a poisson regression and then correlate that graphic with its corresponding incidence rate ratio. I've achieved this for most of my plots. However for one of them, the incidence rate…

Testing the difference between marginal effects calculated across factors

I'm trying to test the difference between two marginal effects. I can get R to calculate the effects, but I can't find any resource explaining how to test their difference. I've looked in the margins documentations and other marginal effects…

Predicting probability of disease according to a continuous variable adjusting by confusing variables

I have a doubt regarding to the R package "margins". I'm estimating a logistic model: modelo1 <- glm(VD ~ VE12 + VE.cont + VE12:VE.cont + VC1 + VC2 + VC3 + VC4, family="binomial", data=data) Where: VD2 is a dichotomous variable (1 disease / 0 not…
