🚨 New function 🚨 @vincentab.bsky.social's marginaleffects 📦 is great for generating quantities of interest from your model. I've long wanted something similar to plot_predictions() for my gratia 📦 Introducing conditional_values() 🎉 gavinsimpson.github.io/gratia/refer... #RStats #GAMs #mgcv 1/6
The image shows the result of a call to the conditional_values() function where the GAM contains a factor by smooth. In this figure, predicted values from the model conditional on values of x2 are shown for two levels of the factor fac. As we're conditioning on two variables, we include the group means for the 2 levels of fac, plus the smooth for each category. This model also includes a smooth effect of x0. As we don't condition on this covariate, it will be set to a typical representative value (value of observation closest to the median of x0).

The code to produce both images is below. This image is created by the last line of the code. 

# packages
library("mgcv")
library("gratia")

# categorical conditions are also handled
df <- data_sim("eg4", seed = 2)
m2 <- gam(y ~ fac + s(x2, by = fac) + s(x0), data = df, method = "REML")
cv <- conditional_values(
  m2,
  condition = list("fac", x2 = "fivenum")
)
# plot - we see a discrete x axis with five estimates per level of fac
cv |> draw()

# in this example we condition on `x2` and `fac %in% c(2,3)`
cv <- conditional_values(
  m2,
  condition = list("x2", fac = 2:3)
)
# plot - smooths of `x2` for `fac == 2` and `fac == 3`
cv |> draw()The image shows the result of a call to the conditional_values() function where the GAM contains a factor by smooth. In this figure, predicted values from the model conditional on values of the factor fac are shown for different values of the covariate x2. As we're conditioning on two variables, but focusing on fac, we summarise x2 by default using its Tukey's five number summary, hence there are 5 estimates per category (level) of fac. This model also includes a smooth effect of x0. As we don't condition on this covariate, it will be set to a typical representative value (value of observation closest to the median of x0).

The code to produce both images is below. This particular image is created by the first call to the draw(). 

# packages
library("mgcv")
library("gratia")

# categorical conditions are also handled
df <- data_sim("eg4", seed = 2)
m2 <- gam(y ~ fac + s(x2, by = fac) + s(x0), data = df, method = "REML")
