### Interpretation of ALE plots

I'm computing the ALE plots for a dataset where the features are strongly correlated. All features are positively correlated with the response variable. So I expect the ALE plots obtained through the ...

### Why individual fixed effect method is not estimating average marginal effects (panel data)?

I am using an individual fixed effect method in a panel data. I look whether the working hours changed differently between men and women following the 2008 financial crisis. Here is a simple model in ...

### emmeans - joint effects of interaction terms

I would like to see the joint effects of an interaction term. I tried joint_tests() but it gives f ratios. However, I would prefer Incidence Rate Ratios (IRR) because the rest of my results section ...

### Marginal Effects with Lagged data

I have a panel data model with lagged dependant and independent variables. I am looking for ways to calculate marginal effects. Here is a simplified formula: Y = 2 lagged(Y) + 3 lagged (X1) + 4 X1 + 5 ...

### Signs of MarginalEffects and CoefficientEstimates in Multivariate Probit

Could someone explain that the sign of coefficient estimates and their corresponding marginal effects in the Multivariate Probit Model is the same or they could be different? IF they are different, ...

### What do you call effects calculated from regression coefficients including interactions but excluding main effects?

Imagine a regression model with this formula: $$y_i = \alpha + \beta_1x_i + \beta_2w_i + \beta_3x_iw_i$$ , i.e. a model with two categorical predictors and the interaction between the two. I reckon ...

### Why are standard errors larger for conditional effects versus marginal effects?

I am estimating the conditional and marginal effects for a continuous by continuous interaction in a linear mixed effects model. The standard errors for the conditional effects are much larger than ...
