Statistical Inference II

 

CO 103:  Learn the Cramer-Rao Inequality, Rao Blackwell and Lehmann Scheffe theorems and their applications in obtaining Minimum Variance Unbiased and Minimum Variance Bound estimators. 

 

CO 104: Obtain the point estimator and interval estimator for the unknown population parameters.

 

CO 105: Apply the concept of Neyman-Pearson fundamental lemma, in the context of hypothesis testing for Binomial, Poisson, Normal, and Exponential populations, for finding the best critical region.
