glance.pmrm_fit: Glance at a PMRM.

In pmrm: Progression Models for Repeated Measures

Glance at a PMRM.

Description

Return a one-row tibble of model comparison metrics for a fitted PMRM.

Usage

## S3 method for class 'pmrm_fit'
glance(x, ...)

Arguments

x	A fitted model x of class "pmrm_fit".
...	Not used.

Value

A tibble with one row and columns with the following columns:

• model: "decline" or "slowing".

• parameterization: "proportional" or "nonproportional".

• n_observations: number of non-missing observations in the data.

• n_parameters: number of true model parameters.

• log_likelihood: maximized log likelihood of the model fit.

• deviance: deviance of the fitted model, defined here as -2 * log_likelihood.

• aic: Akaike information criterion.

• bic: Bayesian information criterion.

This format is designed for easy comparison of multiple fitted models.

    data = simulation,
    outcome = "y",
    time = "t",
    patient = "patient",
    visit = "visit",
    arm = "arm",
    covariates = ~ w_1 + w_2
  )
  glance(fit)
