: Specification summary.- setfixed<-
`signature(object = "ARFIMAspec", value = "vector")`

: Sets the fixed parameters (which must be supplied as a named list).- setstart<-
`signature(object = "ARFIMAspec", value = "vector")`

: Sets the starting parameters (which must be supplied as a named list).- setbounds<-
`signature(object = "ARFIMAspec", value = "vector")`

: Sets the parameters lower and upper bounds, which must be supplied as a named list with each parameter being a numeric vector of length 2 i.e. "ar1"=c(-1,1)). If the vector is of length 1, then this is assumed to be the lower bound, and the upper bound will be set to its default value prior to estimation.- uncmean
`signature(object = "ARFIMAspec")`

: Returns the unconditional mean of a specification which has been assigned fixed parameters.
