Good afternoon,
Could you please tell me what is the difference between the calculation of the R-factor and the NSS ?
I found that R-factor is equal to : sum((data - fit)^2)/sum(data^2) and NSS = sum((data - fit)^2)/sum(data^2)*100
But when I compare the R-factor obtained by Athena and the NSS divided by 100 (calculated by myself) I didn't find the same results.
Did I make a mistake somewhere.
Thank you for your answer.
As you might imagine, it would be very difficult to answer a question about the comparison you made without seeing more details. Please post data (perhaps an Athena project file) and a detailed description of what you actually did, what result you got, and what result you expected to get. Cheers, --Matt
