Modeli wenye kuongezeka sifuri (Zero-Inflated Model)

Modeli wenye kuongezeka sifuri ni mchanganyiko wa vipengele viwili vya urejeshaji (regression) unaoundwa kwa ajili ya matokeo ya hesabu (count outcomes) ambayo yana idadi kubwa zaidi ya sifuri kuliko modeli ya kawaida ya Poisson au negative binomial inavyoweza kukidhi. Kipengele kimoja ni mchakato wa binary unaozalisha sifuri za kimuundo (structural zeros); kingine ni mchakato wa hesabu unaozalisha sifuri na hesabu chanya.
