Calculate and visualize the predicted values (marginal effects) of a variable, potentially conditional on the levels of another variable (interaction).
Arguments
- fit
Model fit object (e.g., `mcmc_fit`, `map_fit`).
- effect
Name of the variable to visualize (e.g., "X1" or "X1:X2").
- prob
Probability for the credible/confidence interval (default is 0.95).
- sd_multiplier
Numeric. Multiplier for standard deviation when splitting continuous moderators (default is 1).
- ...
Additional arguments.
