Advanced Mathematical Statistics Notes for MS/MPhil

“Advanced Mathematical Statistics” typically refers to a higher-level study in statistical theory that delves into sophisticated methods and theoretical foundations of statistical inference.

Here is an explanation of the key components mentioned in your question:
  1. Estimation:
    • Criteria and Methods for Estimators: This involves understanding the properties and criteria for good estimators, such as unbiasedness, efficiency, and consistency.
    • Classical and Newer Methods of Estimation: Exploring traditional estimation methods and newer techniques developed in recent statistical research.
    • Deriving Estimators (Bayes Methods, MLE): The derivation of estimators using different approaches, including Bayesian methods and MLE.
  2. Cramer-Rao and its Extension:
    • Cramer-Rao Bound: A theoretical limit on the variance of any unbiased estimator of a parameter.
    • Extension of Cramer-Rao Bound: Modifications or extensions to the Cramer-Rao bound for specific scenarios.
  3. Bias Reduction by Jackknifing, Rao-Blackwellization, Basu’s Theorem:
    • Jackknifing: A resampling technique used for bias reduction and variance estimation.
    • Rao-Blackwellization: Improving estimators by taking conditional expectations.
    • Basu’s Theorem: A result in mathematical statistics providing conditions under which conditional independence implies independence.
  4. Estimation in Parametric and Nonparametric Methods:
    • Parametric Methods: Estimation techniques assuming a specific parametric model for the data.
    • Nonparametric Methods: Estimation without assuming a specific parametric form for the underlying distribution.
  5. Testing Hypotheses:
    • Parametric Methods: Hypothesis testing within the context of specific parametric models.
    • Neyman-Pearson Lemma: A fundamental result in hypothesis testing that provides guidelines for constructing tests with optimal properties.
    • Uniformly Most Powerful Tests: Tests that maximize power uniformly over a parameter space.
    • Unbiased Tests: Hypothesis tests that maintain unbiasedness.
  6. Large Sample Theory, Asymptotically Best Procedures:
    • Large Sample Theory: Theoretical study of statistical procedures as sample sizes become large.
    • Asymptotically Best Procedures: Procedures that become optimal as sample sizes tend to infinity.
  7. Testing Under Nuisance Parameters, Review of Tests for Normal Distribution:
    • Nuisance Parameters: Parameters that are not of primary interest but need consideration in testing.
    • Review of Tests for Normal Distribution: Evaluating statistical tests specifically designed for normal distribution data.

In summary

“Advanced Mathematical Statistics” covers a wide range of sophisticated statistical concepts and methods, emphasizing theoretical foundations and advanced techniques used in statistical inference. The topics mentioned involve a deep understanding of estimation, hypothesis testing, large sample theory, and the application of these methods in various contexts, from parametric models to nonparametric approaches.
