Hi all, While running the anscombe.test in R, I'm getting an error of *Error in if (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed* for a few time series columns whereas for most of the series the function is working fine. I have checked for those specific columns for missing values. However, there is no NA/NAN value in the dataset. I have also run kurtosis for those time series and I can get results. I have noticed the same issue was reported in the following post for python (scipy.stat) and the report mentions that there is a bug in moments package in R. I was wondering whether the issue has been resolved. https://github.com/scipy/scipy/issues/1950 Could anyone please help me with the error? I look forward to hearing from you.

moments::anscombe.test(x) does give errors when x has too few values or if all the values in x are the same> moments::anscombe.test(c(1,2,6))Error in if (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed> moments::anscombe.test(c(2,2,2,2,2,2,2,2))Error in if (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed You can use tryCatch() to return some special value where these errors occur. E.g., use tryCatch(anscombe.test(x), error=function(e) list(p.value=NA)) instead of ascombe.test (this assumes you will only look at p.value later - add other entries as needed.). -Bill On Thu, Oct 15, 2020 at 12:09 PM Sania Wadud <sania.wadud at gmail.com> wrote:> Hi all, > > While running the anscombe.test in R, I'm getting an error of *Error in if > (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed* for a > few time series columns whereas for most of the series the function is > working fine.

Hi Bill, Thanks for prompt reply and letting me know a way around it. I have more than 1200 observations and not all the values are the same. However, my data points are quite similar, for example, 0.079275, 0.078867, 0.070716 in millions and etc. I have run the data without converting it to millions and I still get the same error message. As I have kurtosis value, it should be fine for the time being. However, in case if you have any other explanation behind the error, I will highly appreciate it.
