Usage

depvar(object, ...)

Arguments

An object that has some response/dependent variable.

...

Other arguments fed into the specific methods function of the model.

See Also

model.matrix, vglm.

Examples

pneumo = transform(pneumo, let = log(exposure.time))
(fit = vglm(cbind(normal, mild, severe) ~ let, propodds, pneumo))
fit@y        # Sample proportions (not recommended)
depvar(fit)  # Better than using fit@y; dependent variable (response)
weights(fit, type = "prior") # Number of observations
