Methods

Public methods

• NBData$new()

• NBData$clone()

---

Method new()

Create a new [`NBData`] object.

Usage

NBData$new(Y, X, X0 = NULL)

Arguments

Y

the matrix of responses (called Y in the model).

X

design matrix (called X in the model).

X0

zero-inflation design matrix, if applicable.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

NBData$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
