TSDELTAP {bimets}R Documentation

Time Series Percentage Lag Differences (Delta Percentage)

Description

This function returns the O-order, L-lag percentage differences of the input time series. If the input time series frequency is a multiple of the L lag argument, then it is possible to set the argument ANNUALIZE=TRUE in order to have the percent changes returned at annual rates, i.e. raised to power of frequency/L.

Usage

TSDELTAP(x = NULL, L = 1, ANNUALIZE = FALSE, avoidCompliance = FALSE, ...)

Arguments

x

Input time series that must satisfy the compliance control check defined in is.bimets.

L

Lag.

ANNUALIZE

If TRUE the percent changes are returned as annual rates, i.e. raised to the power of frequency/L

avoidCompliance

If TRUE, compliance control check of input time series will be skipped. See is.bimets

...

Backward compatibility.

Value

This function returns a BIMETS time series.
