nardl: Nonlinear ARDL function

Description

Nonlinear ARDL function

Usage

nardl(formula, data, ic = c("aic", "bic"), maxlag = 4, graph = FALSE, case = 3)

Arguments

formula

food~inf or food~inf|I(inf^2)

data

the dataframe

ic

: c("aic","bic") criteria model selection

maxlag

maximum lag number

graph

TRUE to show stability tests plot

case

case number 3 for (unrestricted intercert, no trend) and 5 (unrestricted intercept, unrestricted trend), 1 2 and 4 not supported

Examples

# NOT RUN {
############################################
# Fit the nonlinear cointegrating autoregressive distributed lag model
############################################
# Load data
data(fod)
############################################
# example 1:auto selected lags (maxlags=TRUE)
############################################
reg<-nardl(food~inf,fod,ic="aic",maxlag = 4,graph = FALSE,case=3)
summary(reg)

############################################
# example 2: Cusum and CusumQ plot (graph=TRUE)
