I have two problems I'd need some help with.
I have a column vector (25 x 1) with positive and negative values. It has the following values:
First problem: Out of these values, I would first like to calculate the average (mean) of all the values that are not negative.
I tried the following script, but it gives a weird answer of 0,68:
OnlyPositives = profit>=0;
avgProfitNoLoss = mean(OnlyPositives)
I don't know why it gives me the answer of 0,68 so the first question is how I can correct this.
The next step then is to calculate the average of the values that are zero and the values that are negative. But, the first problem above needs to be addressed first.
Thank you in advance for any help/suggestions!
