All I can say is that this is working:
As far as I can see the problem comes from the very first line of your data:
So instead you might try:
HistogramDistribution[dataout[[2 ;;, {1, 2}]], "Scott"]
Hope that helps, regards -- Henrik
Sorry, may be I did not present the problem clearly. Now I have deleted the first line of the .txt file, the problem remains.
I have tried 11.0 and 11.1.1.0 , both failed. Could you upload your code and the output results? Thank you.
