In greybox: Toolbox for Model Building and Forecasting

Greybox classes checkers

Description

Functions to check if an object is of the specified class

Usage

is.greybox(x)

is.alm(x)

is.occurrence(x)

is.greyboxC(x)

is.greyboxD(x)

is.rollingOrigin(x)

is.rmc(x)

is.scale(x)

Arguments

x	The object to check.

Details

The list of functions includes:

• is.greybox() tests if the object was produced by a greybox function (e.g. alm / stepwise / lmCombine / lmDynamic);

• is.alm() tests if the object was produced by alm() function;

• is.occurrence() tests if an occurrence part of the model was produced;

• is.greyboxC() tests if the object was produced by lmCombine() function;

• is.greyboxD() tests if the object was produced by lmDynamic() function;

• is.rmc() tests if the object was produced by rmc() function;

• is.rollingOrigin() tests if the object was produced by ro() function;

• is.scale() tests if the object is of the class "scale" (produced by alm or sm in case of heteroscedastic model);

Value

TRUE if this is the specified class and FALSE otherwise.

Examples

xreg <- cbind(rlaplace(100,10,3),rnorm(100,50,5))
xreg <- cbind(100+0.5*xreg[,1]-0.75*xreg[,2]+rlaplace(100,0,3),xreg,rnorm(100,300,10))
colnames(xreg) <- c("y","x1","x2","Noise")

ourModel <- alm(y~x1+x2, xreg, distribution="dnorm")

is.alm(ourModel)
is.greybox(ourModel)
is.greyboxC(ourModel)
is.greyboxD(ourModel)
