ggeffects 1.7.2

Breaking changes

• The deprecated argument ppd was removed.

• Some of the deprecated arguments in plot() were removed.

• Pooling functions now use the model's degrees of freedom to calculate the
  critical values for the confidence intervals.

Changes

• test = "slope" (or test = "trend") are aliases in test_predictions() for
  test = NULL with numeric predictors.

• predict_response() (and ggpredict(), ggemmeans() and ggeffect()) get
  an argument bias_correction, to correct for bias when back-transforming
  predictions for non-Gaussian mixed models.
