FITTING OF DAILY RAINFALL OCCURRENCE AS AN ALTER- NATING RENEWAL PROCESS

摘要

A probability model suggested by J.R. Green that the sequence ofdry and wet spells forms an alternating renewal process, withexponential density functions for the lengths of dry and wet spellshas been fitted to the daily rainfall data, recorded at Sunanganj. Agoodness of fit test has been performed and compared with the Markovchain probability model suggested by Gabriel and Neumann and foundthat both the models do not fit well with the observed data .
