Abstract: It is shown that for a small sample size, when the maximum likelihood estimators lose its asymptotic properties, a more accurate point and interval estimation of the Poisson distribution parameter requires a direct investigation of the properties of the normalized likelihood function. Alternative point and interval estimates of the distribution parameter are obtained.

Keywords: Normalized likelihood function, Poisson type distribution, point estimate, confidence interval
