When I analyzed a large data set(see the attachment) using the function "HistogramDistribution" dataout = Import["/Users/apple/Desktop/dataOut.txt", "Table"]; HistogramDistribution[dataout[[All, {1, 2}]], "Scott"] an error occurs: Thread::tdlen: Objects of unequal length in (1/99953){0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,<<42>>} {<<1>>} cannot be combined. And the output data distribution becomes a mess. The strange thing is, when I change the bspec "Scott" to "Sturges" or "Automatic", everything works. HistogramDistribution[dataout[[All, {1, 2}]], "Sturges"] Now for some practical reasons, I have to use "Scott" to analyze the data. So could anyone help me solve this? Thanks a lot. Attachments:

Right, Solved! 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"]

All I can say is that this is working:
