Efficiency of Some Modified Ratio and Product Estimators Using Known Value Of Some Population Parameters.
A.A. Adewara, Rajesh Singh, Mukesh Kumar

Khoshnevisan et al (2007) proposed a general family of estimators for estimating population means using known value of some population parameter(s) which after some substitutions led to some ratio and product estimators initially proposed by Sisodia and Dwivedi (1988), Singh and Tailor (2003), Pandey and Dubey (1988) etc. Adopting Adewara (2006) in improving these estimators observed that all these modified ratio and product estimators perform better than the earlier proposed ones.
