Hi
Did you mean wald.test? If not, what is wal.test?
Instead of attaching anything (which is usually stripped from the mail), you
should copy your code directly to your mail and preferably together with your
data.
See ?dput
Cheers

We need some information that is missing in order to help you.
PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

thankx to everyone for your valuable suggestions. one query regarding the
GARCH model.
I have applied the GARCH model for the same data that I send you all . and
my results coming like
Error in .sgarchfit(spec = spec, data = data, out.sample = out.sample, :
ugarchfit-->error: function requires a
Assuming the input data.frame, DF, is of the form shown reproducibly
in the Note below, to convert the series to zoo or ts:
library(zoo)
# convert to zoo
z <- read.zoo(DF)
# convert to ts
as.ts(z) #
Note:
DF <- structure(list(year = c(1980, 1981, 1982, 1983, 1984), cnsm = c(174,
175, 175, 17
oky.. thank you very much to all of you

You can just use the same code that I provided before but now use your
dataset. Like this
df <- read.csv(file="data2.csv",header=TRUE)
dates <- as.Date(paste(df$year,"-01-01",sep=""))
myXts <- xts(df,order.by=dates)
head(myXts)

thanks, eric../ actually I have the data which have not specify the months.
therefore i bound to declare is in yearly data. i also attached a sample
data set that may be helpful for you to providing suggestions. thank you

Do you really need to convert your data to time series/xts/zoo? I don’t know
you try what kind
You did not provide the data frame so I will first create one and then use
it to create an xts
library(xts)
df <- data.frame( year=1980:2009, cnsm=sample(170:180,30,replace=TRUE),
incm=rnorm(30,53,1), wlth=rnorm(30,60,1))
dates <- as.Date(paste(df$year,"-01-01",sep=""))
myXts <-
