List of arguments (see Note).

##### Note

`merPredD(...)`

is a short form of `new("merPredD", ...)`

to create a new `'>merPredD`

object and the
`...`

must be named arguments, ```
(X, Zt, Lambdat, Lind,
theta,n)
```

:

`X`

:dense model matrix for the fixed-effects parameters, to be stored in the

`X`

field.`Zt`

:transpose of the sparse model matrix for the random effects. It is stored in the

`Zt`

field.`Lambdat`

:transpose of the sparse lower triangular relative variance factor (stored in the

`Lambdat`

field).`Lind`

:integer vector of the same length as the

`x`

slot in the`Lambdat`

field. Its elements should be in the range 1 to the length of the`theta`

field.`theta`

:numeric vector of variance component parameters (stored in the

`theta`

field).`n`

:sample size, usually

`nrow(X)`

.
