Prediction for a growth mixture model (not implemented) — predict.latents_growth

Predictions for new persons are not implemented yet. The fitted class trajectories and each fitted person's own predicted curve are tables of get_results.latents_growth_mixture(): "trajectories" and "individual".

Usage

# S3 method for class 'latents_growth_mixture'
predict(object, ...)

Arguments

object: A latents_growth_mixture fit.
...: Unused.

Value

Never returns; raises latents_unsupported_prediction.

Examples

few_students <- subset(growth_scores, student <= 60)
fit <- mixture_regression(score ~ wave, few_students, n_classes = 2,
                          id = "student", class_level = "group",
                          random = "intercept", seed = 1)
# Prediction is refused; get_results(fit, "trajectories") has the curves
try(predict(fit))
#> Error : predict() is not implemented for growth mixture models yet. The class trajectories are get_results(x, "trajectories"), and each fitted person's class trajectory and own predicted curve are get_results(x, "individual").
