Hey, I have a sampling problem, for an analysis i have to calculate a revenue growth share. I found an article about sampling with negative numbers very helpfull since i have to work with a sum of revenues that is negative. The article suggests to make all the numbers absolute, but unfortunately this does not solve my problem. Since i am looking at revenue growth shares i want to punish the companies that score 'bad' and reward the companies that score 'good'. therefore it would not make sense for me to gives the same growth percentages (50%) to a score of +1 and -1 in revenue growth.
Simplified; the problem looks as follow; sample (revenue growth)= 2, -3, -4, -1
sum=-6
scenario 1 calculated percentages;
2/abs(-6)
-3/abs(-6)
-4/abs(-6)
-1/abs(-6)
is this correct or should i take this approach;
2/10
-3/10
-4/10
-1/10
I have the problem that both scenario's do not add up to 100%. I need the growth share to calculate z scores. I hope you have a suggestion.
Thank you very much in advance,
Kind regards,
