• Provides margins() for estimating marginal effects.
• Provides oneLRT(), oneWald(), and signifWald() for various tests.
• Provides predict() to compute expected responses.
• Provides summary() to display model estimates and various diagnostics.
• Provides oneplot() to visually compare actual counts and any fitted models.
