errorType function

Functions that extracts type of error from the model

This function allows extracting error type from any model.

errorType(object, ...)

Arguments

• object: Model estimated using one of the functions of smooth package.
• ...: Currently nothing is accepted via ellipsis.

Returns

Either "A" for additive error or "M" for multiplicative. All the other functions return strings of character.

Details

errorType extracts the type of error from the model (either additive or multiplicative).

Examples

xreg <- cbind(rnorm(100,10,3),rnorm(100,50,5))
xreg <- cbind(100+0.5*xreg[,1]-0.75*xreg[,2]+rnorm(100,0,3),xreg,rnorm(100,300,10))
colnames(xreg) <- c("y","x1","x2","Noise")
ourModel <- alm(y~x1+x2,as.data.frame(xreg))
