Attempted to access PriorProb(8); index out of bounds because numel(PriorProb)=7.

Error: Attempted to access PriorProb(8); index out of bounds because numel(PriorProb)=7.

What does this error mean? I got it when I put in:

W(i,1) = -0.5 * Temp * GroupMean(i,:)' + log(PriorProb(i));

I have 7 prior probability numbers that I used and this error showed up. Need help!!!

You must prevent the index variable i from reaching a value of 8.

Thanks so much!!!

[Lester Lim]

But how exactly do I do that?

[Matt J]

How exactly are you setting i right now? If it's a loop variable, make sure you're doing

 for i=1:7,...,end

and not

 for i=1:8,...,end

[Lester Lim]

yup, it worked!!! Thanks!

[Lester Lim]

After this I would need to combine it with a cross validation method which dosen't utilise statistics toolbox. Would u happen to know any?

[Matt J]

Maybe this, or other FEX contributions? I'm not a hard-core statistician...

Thanks for the help! Im trying it right now and welcome other suggestions...
