Hi:
The input to jarque.bera.test() is a numeric vector or time series. Try
running the function str() on your input object to see if it is of the
correct type. If you have a vector that is not numeric or a time series
object, you need to convert it to one with something like as.numeric(myvec).
The function won't work directly on a data frame or matrix, for example. If
it still doesn't work after you've tried to make changes, please provide a
reproducible, small example that illustrates the problem.
Here's an illustration of what I mean:
x <- rnorm(100)
xx <- ts(x)
> class(x)
[1] "numeric"
> class(xx)
[1] "ts"
> library(tseries)
> jarque.bera.test(x)
Jarque Bera Test
data: x
X-squared = 7.7779, df = 2, p-value = 0.02047
> jarque.bera.test(xx)
Jarque Bera Test
data: xx
X-squared = 7.7779, df = 2, p-value = 0.02047
xxx <- matrix(x, ncol = 2)
> jarque.bera.test(xxx)
Error in jarque.bera.test(xxx) :
x is not a vector or univariate time series
HTH,
Dennis
