A kind respondent mentioned that I gave no data for this data set. Here is a
subset in CSV format:
"","levels","m101","m101111"
"1",0.15,0.00166736248903737,0.00525782746279257
"2",0.16,0.000671421429082792,0.00263263808833129
"3",0.17,0.000248914508386666,0.00125478603676572
"4",0.18,8.62700534705944e-05,0.000575729980347196
"5",0.19,2.71841670884316e-05,0.000251684211328049
Here is the CSV file. I hope it's OK to send it to the mailing list.
Thanks again,
KW
