Two functions within a if statement

I would like to run different statistical tests within an if statement. If certain assumptions were met run a parametric test, if not a non-parametric test should be run. The script I present below runs both analyses.

for ic = 1:size (Dg,2);
    if Dg (1,ic) == 1 
            [p, h, stats] = signrank (Dd (:,ic),De(:,ic)); 
            results(1,ic)=p; 
            results(2,ic)=h;
            results(3,ic)=stats.zval; 
            results(4,ic)=stats.signedrank; 
    else
           [h1,p1,ci1,stats1] = ttest(Dd,De);
    end 
end

In the end, I get two sets of outputs, and it looks like both statistical tests were run either Dg is equal to zero or not. I was expecting to a few missings in each set of outputs.

What is your question? It seems your code should already be working, even if the second part will overwrite its previous result every time it runs.

Hi Rik,

It is true, it works.

It seems to run both analyses even when Dg is different from 1. I was expecting two different set of results with a few missings in each.

Thanks

There will be empty rows in your results matrix if any(Dg(1,ic)~=1)

For the else part, you could employ the same strategy of indexing the result, either to the same matrix or a different one. Currently you are overwriting the results.

Many thanks.
