ESTIMATION OF PARITY SPECIFIC FERTILITY RATES UNDER DIFFERENT FECUNDITY LEVELS
Keywords:
Fertility Analysis, Parity Progression Ratio, Birth Interval Distribution.Abstract
A number of attempts have been made to describe probabilistic behaviour of couple fertility in a given period of time (0,T). Singh et al. (1974), Singh (1964), Bhattacharya (1986), Pathak (1999) and Khan and Raeside (1998) have built the models to enhance the impact of birth intervals and fertility rates. Biswas (1980) considered the waiting time distribution as the convolution of several Poisson distributions with variable parameters Ȝi. In the proposed study, it has been derived to estimate parity wise fertility rates under different fecundity levels based on renewal theory approach by considering the hazard rates of particular parity.
