Can I find likelihood function of an objective function?
A lot depends on the details of these models, but one way to proceed would be in terms of the error scores. Consider the full mo...

ANOVA result No p-value.
The problem is that the full model has 90 parameters and predicts a separate mean for each of the 3*3*10 conditions. But you onl...

I am having trouble with errors in the array used for anova analysis
Looks like g1 should be a numerical vector, not a cell array (i.e., square brackets instead of curly brackets). e.g., g1 = [1,2...

How do I calculate the signal to noise ratio of a signal without knowing the noise of the signal?
I'm not sure whether this fits your situation, but one way to estimate the noise is to subtract the average of the epochs from e...

Using a specific number of digits
Maybe by "report k" you are referring to printing it, in which case this should work for k=1:100 fprintf('%03d\n',k) end

How to computing confidence bounds of the regression model using the bootstrap method
I'm assuming that your figure shows t on the horizontal axis and y on the vertical. The problem is that bootci is giving you co...

How do I update an inherited property in both the SuperClass and SubClass simultaneously in real time?
The superclass/subclass relationship is a little different than you think. When you make SUP and SUB, these are completely diff...

Anova analysis with blocking
You can do this with fitlm as long as you want to test for the effect(s) of interest within a standard linear RCBD model. The h...

How to use num2str inside text with latex interpreter?
I think you need square brackets like this to assemble all the characters into a single string text(4,5,['\$L_{',num2str(i),'}\$'...

if I set model as 'linear' in 'anovan', is 'anovan' equivalent to applying respectively 'anova1' to the factors?
no, those are not equivalent, as you should be able to verify by applying them both to the same dataset. With its default 'linea...

Plot a cumulative distribution with a symmetric logarithmic scale centred at 50%

Error when using: parmHat = wblfit(x)
The problem is that your x vector has some nan's in it, and wblfit can't handle those. Try y = x(~isnan(x)); parmHat = wblfit...
