Ttest problem with alpha
조회 수: 15(최근 30일)
So I'm trying to run a one-sample test so that I can determine the confidence intervals at one standard deviation away. However I keep getting the error 'ALPHA must be a scalar between 0 and 1' for the following code.
[ ho1, pv1, ci1, stat1 ] = ttest( New_cor.h, mean( New_cor.h ),'Alpha', 0.32 );
I've tried replacing the 0.32 with other values between 0 and 1 including 0.05 and 0.01 but I still get the same error. If I don't include 'Alpha' and run the ttest as the default 0.05, it works. Any ideas?

you do not need to pass 'Alpha' to the function, you are getting the error because you are trying to pass a string when it is expecting a number. Just do this:
[ ho1, pv1, ci1, stat1 ] = ttest( New_cor.h, mean( New_cor.h ), 0.32 );
