WebJul 19, 2024 · We discussed what it means for a model to be “nested” by considering the case of modeling a set of coins flips under the assumption that there is one coin versus two. Finally, we empirically explored Wilk’s Theorem to show that LRT statistic is asymptotically chi-square distributed, thereby allowing the LRT to serve as a formal hypothesis test.
