Confidence levels for glmfit - glmval or fitglm using the Likelihood Ratio method

After several days and many hours of researching and googling, I am unable to determine how I could find confidence levels using the Likelihood Ratio for either glmfit - glmval or fitglm. I know it can be done in R, but I don’t see that capability in Matlab. Does it exist? Neither glmval nor coefCI appear to use or have options for using the Likelihood Ratio method. And paramci does not appear to work with a GeneralizedLinearModel object.
Thanks for any help you can provide.

Hi Craig,
Upon looking up the documentation for the relevant functions which can be used to serve your functionality, I unfortunately couldn't find anything that finds the confidence levels using the Likelihood ratio.
On the other hand, I did see that "coefCI" uses the Wald Method to determine the confidence intervals, which as far as I could find, is an approximation of the Likelihood Ratio test.
Now as a workaround as you said, there is a functionality in R for the same, I can suggest you the following:
This is a filexchange developed to create a link between MATLAB and R, using which you can get the variables from R, and also run scripts there. This can help you keep the entire pipeline in MATLAB, with just the confidence intervals being calculated in R.
Hope this helps!
