How to use Excel to do likelihood ratio chi-squared test?
I know I can use the "Chitest" function to do chi-squared test, but I have
no idea how to do likelihood ratio test using Exel functions.

In general, Chi-square for the LRT is an asymptotic approximation
 http://en.wikipedia.org/wiki/Likelihood_ratio_test

Using the information at that link, you can calculate the LRT and then use
CHIDIST to evaluate its significance.
