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)
