Likelihood Degeneracy

Likelihood Degeneracy is a phenomenon in statistical inference whereby the likelihood function becomes ill-defined or collapses to a degenerate form, losing discriminatory power among parameter values due to structural insufficiency in the model or insufficient information in the data.
