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.

Best wishes,
