Data Models — datamods • bage

The models for rates, probabilities, or means created with functions mod_pois(), mod_binom(), and mod_norm() can be extended by adding data models, also referred to as measurement error models.

Details

Function	Assumptions about measurement error	Poisson	Binomial	Normal
`set_datamod_miscount()`	Reported outcome has undercount and overcount	Yes	No	No
`set_datamod_undercount()`	Reported outcome has undercount	Yes	Yes	No
`set_datamod_overcount()`	Reported outcome has overcount	Yes	No	No
`set_datamod_noise()`	Reported outcome unbiased, but with positive and negative measurement errors	Yes*	No	Yes
`set_datamod_exposure()`	Reported exposure unbiased, but with positive and negative measurement errors	Yes*	No	No

*Models with no dispersion term for rates.
