predict.DALSM: Prediction based on a DALSM model

In DALSM: Nonparametric Double Additive Location-Scale Model (DALSM)

Prediction based on a DALSM model

Description

Estimated conditional mean and standard deviation of the response based on a DALSM object for given covariate values in a data frame 'newdata'. Conditional quantiles can also be computed.

Usage

## S3 method for class 'DALSM'
predict(object, newdata, probs, ...)

Arguments

object	a DALSM.object.
newdata	an optional data frame in which to look for variables with which to predict. If omitted, the covariate values in the original data frame used to fit the DALSM model are considered.
probs	probability levels of the requested conditional quantiles.
...	further arguments passed to or from other methods.

Value

Returns a list containing:

• mu : ⁠ ⁠estimated conditional mean.

• sd : ⁠ ⁠estimated conditional standard deviation.

• quant : ⁠ ⁠estimated quantiles (at probability level probs) of the fitted conditional response in the DALSM model.

• qerr : ⁠ ⁠quantiles (at probability level probs) of the fitted error distribution in the DALSM model.

• probs : ⁠ ⁠a reminder of the requested probability levels for the fitted quantiles.

Examples

require(DALSM)

resp = DALSM_IncomeData[,1:2]
fit = DALSM(y=resp,
            formula1 = ~twoincomes+s(age)+s(eduyrs),
            formula2 = ~twoincomes+s(age)+s(eduyrs),
