Key Syllabus Coverage (Official IGNOU Curriculum)

• Block-1: Uniformly Minimum Variance Unbiased Estimators (UMVUE)
  • Definition and properties of UMVUE with rigorous proofs for exponential families.
  • Application of Lehmann-Scheffé theorems in deriving unbiased estimators.
  • Practical examples: Estimating variance in normal distributions, Poisson parameter estimation.
• Block-2: Neyman-Pearson Lemma and Sequential Testing
  • Derivation of the Neyman-Pearson lemma with detailed mathematical steps.
