[R] Usingloglikelihood to Infer which distributions fits best to data
Hi, Below are the average loglikelihood of mixture model over 5 components (k=5). The loglikelihood are learnt using EM over three kinds of distribution: Lognormal, Gamma, and Normal. Since the average loglikelihood for Lognormal is the highest over Gamma and Normal. Is it safe to infer that Lognormal is the best distribution to fit the data? .
