\usage{
\method{predict}{lvm}(
object,
x = NULL,
y = NULL,
residual = FALSE,
p,
data,
path = FALSE,
quick = is.null(x) & !(residual | path),

)
}
\arguments{
\item{object}{Model object}
\item{x}{optional list of (endogenous) variables to condition on}
\item{y}{optional subset of variables to predict}
\item{residual}{If true the residuals are predicted}
\item{p}{Parameter vector}
\item{data}{Data to use in prediction}
\item{path}{Path prediction}
\item{quick}{If TRUE the conditional mean and variance given covariates are returned (and all other calculations skipped)}
\item{\dots}{Additional arguments to lower level function}

\examples{
m <- lvm(list(c(y1,y2,y3)~u,u~x)); latent(m) <- ~u
d <- sim(m,100)
e <- estimate(m,d)
## Conditional mean (and variance as attribute) given covariates
r <- predict(e)
## Best linear unbiased predictor (BLUP)
r <- predict(e,vars(e))
## Conditional mean of y3 giving covariates and y1,y2
r <- predict(e,y3~y1+y2)
## Conditional mean gives covariates and y1
r <- predict(e,~y1)
## Predicted residuals (conditional on all observed variables)
r <- predict(e,vars(e),residual=TRUE)
