zicreg-class: The zicreg S4 Class

In bizicount: Bivariate Zero-Inflated Count Models Using Copulas

The zicreg S4 Class

Description

Note that zicreg objects are, in general, S3. However, this S4 class is defined for compatability with texreg. Interaction with zicreg objects should generally use S3 syntax, but the below objects have the same name in both the S3 and S4 objects (but are in a list for S3).
