Hello all,
I tried to extract the p-value from adf.test in tseries; however, I got the
error message such as
> ht=adf.test(list.var$aa)
> ht$p-value
Error in ht$p - value : non-numeric argument to binary operator
> ht
Augmented Dickey-Fuller Test
data: list.var$aa
Dickey-Fuller = -2.3147, Lag order = 4, p-value = 0.4461
alternative hypothesis: stationary
> ht$data
[1] "list.var$aa"
> ht$p-value
Error in ht$p - value : non-numeric argument to binary operator
> ht$p
NULL
I do not have problem extracting the data in ht, but why not p-value? Is that
because the "-" between "p" and "value"?
Thanks,
Rebecca
