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.
All I can say is that this is working:
This appears to work for me in Mathematica 11.3. What version are you using?
I have tried 11.0 and 11.1.1.0 , both failed. Could you upload your code and the output results? Thank you.
It looks like there was a bug in the HistogramDistribution code that was introduced in version 10.4 and fixed in version 11.2. I'm afraid I don't know of a workaround for the affected versions.
And the code I used was:
data = Import["~/Downloads/dataOut_2.txt", "TSV"]; HistogramDistribution[data[[2 ;;, {1, 2}]], "Scott"]
Right, Solved! Thank you!
