I am testing returns on shares, using different ways.
One way is to calculate returns based on daily transactions and then adjust for the time.
Another way is to calculate returns based on intra day transactions.
If I would like to compare the two (ie the difference of the means >0)(to see if there are significant returns) DO i use a paired t test, or a unequal variance t test, or a equal variance test?
And how to I manually calculate those t statistics without using Excel function of ttest()?
Any help would be appreciated
