Two independent random samples are drawn from two Binomial populations with parameters θ1 and θ2, respectively. Ahmed (1991) considered a preliminary test estimator based on maximum likelihood estimator for estimating θ1 when it is suspected that θ1 = θ2,. In this paper we combine minimum phi-divergence estimators as well as phi-divergence test statistics in order to define preliminary phi-divergence test estimators. These new estimators are compared with the classical estimator as well as the pooled estimator.
