predict.tsfm: Predicts asset returns based on a fitted time series factor...

In sangeeuw/factorAnalytics_Avinash: Factor Analytics

Description

S3 predict method for object of class tsfm. It calls the predict method for fitted objects of class lm, lmRob or lars as appropriate.

Usage

## S3 method for class 'tsfm'
predict(object, newdata = NULL, ...)

Arguments

object	an object of class tsfm produced by fitTsfm.
newdata	a vector, matrix, data.frame, xts, timeSeries or zoo object containing the variables with which to predict.
...	optional arguments passed to predict.lm or predict.lmRob, such as se.fit, or, to predict.lars such as mode.

Value

predict.tsfm produces a matrix of return predictions, if all assets have equal history. If not, a list of predicted return vectors of unequal length is produced.

Examples

# load data from the database
data(managers)
# fit the factor model with LS
fit <- fitTsfm(asset.names=colnames(managers[,(1:6)]),
               factor.names=c("EDHEC.LS.EQ","SP500.TR"), data=managers)

pred.fit <- predict(fit)
newdata <- data.frame("EDHEC.LS.EQ"=rnorm(n=120), "SP500.TR"=rnorm(n=120))
rownames(newdata) <- rownames(fit$data)
pred.fit2 <- predict(fit, newdata, interval="confidence")
