Abstract
In this paper, Eggenberger–Polya distribution has been preferred as an alternative to a 2-state Markov Chain model for characterizing persistence behaviour of dry spell for Northern Odisha, India during south-west monsoon season. An attempt has been made to compare performance of the two competing models with reference to their strength to fit the empirical distribution of dry spell length under two goodness-of-fit criteria.
