<pre>The following is the dataset that I was working on and which first alerted me
to the problem.
X Y
----------
240 57
280 48
320 40
360 35
400 30
500 25
600 20
700 17
800 14
1000 11.5
1200 9.5
1500 8
2000 6.7
2500 5.5
3000 4

6000 2
8000 1.2
I used an online power regression calculator
(<a href="https://keisan.casio.com/exec/system/14059931777261">https://keisan.casio.com/exec/system/14059931777261</a>) to get the correct
answers.
Libre Calc results:
a = -1.03774556216783
b = 9.66940331258679
Online calculator results:
a = 15825.903
b = -1.03774556</pre>
