Various Tools for Exchange Rate Regime Classification

Tools for exchange rate regime classification, currently under development.

Keywords
regression
Usage
fxpegtest(model, peg = NULL, …)
Arguments
model

an object of class "fxlm" as returned by fxlm.

peg

character with the name of the currency the target currency is pegged to. By default this is chosen to be the currency with the maximal absolute coefficient.

arguments passed to linearHypothesis.

Details

These tools should help to automate exchange rate regime classification.

The first building block is the function fxpegtest, a simple convenience interface to linearHypothesis. It assess the null hypothesis that only the peg currency has coefficient 1 and all other currencies have coefficient 0.

Examples
# NOT RUN {
## load package and data
library("fxregime")
data("FXRatesCHF", package = "fxregime")

## compute returns for CNY (and explanatory currencies)
## after abolishing fixed USD regime until end of 2005
cny <- fxreturns("CNY", frequency = "daily",
  start = as.Date("2005-07-25"), end = as.Date("2005-12-31"),
  other = c("USD", "JPY", "EUR", "GBP"))

## estimate full-sample exchange rate regression model
fm <- fxlm(CNY ~ USD + JPY + EUR + GBP, data = cny)

## check for plain USD peg:
fxpegtest(fm)
## no deviation from a plain USD peg
# }
