MST-025 IGNOU Solved Assignment 2026-27

MST-025 Solved Assignment: Categorical and Survival Analysis (TMA 100% Verified)

This digital PDF assignment addresses the mandatory 30% course weightage for MST-025, structured to mirror the official IGNOU curriculum blocks for M.Sc. (Applied Statistics). Solutions integrate statistical rigor with practical applications in Natural, Physical, and Life Sciences contexts.

Key Syllabus Blocks Covered

• Block-1: Categorical Data Analysis
  • Binomial and multinomial distributions with real-world examples (e.g., genetic trait inheritance, ecological classification).
  • Chi-square goodness-of-fit and independence tests, including R/SAS implementation for biological survey data.
  • Log-linear models for contingency tables, with applications in epidemiological studies (e.g., disease risk stratification).
• Block-2: Survival Analysis
  • Kaplan-Meier estimator and log-rank test for censored data, illustrated with lifespan studies (e.g., plant growth cycles).
  • Cox proportional hazards model, validated with pharmaceutical trial data (drug efficacy timelines).
  • Accelerated failure time models for environmental degradation studies (e.g., material durability).

Assignment Structure & FAQs

Question Breakdown:

• Section A (500 words): Compare categorical analysis techniques for agricultural yield classification (e.g., crop disease severity).
• Section B (250 words): Derive the Kaplan-Meier survival curve for laboratory rat lifespan data with 20% censoring.
• Section C (100 words): Discuss limitations of the log-linear model in genetic linkage studies.

FAQs

• Q: Are solutions provided in both English and Hindi?

  Yes. The TMA includes bilingual solutions (English/Hindi) with exact translations for statistical terms (e.g., ‘ ’).

• Q: How do I verify the assignment’s compliance with IGNOU’s word limits?

  Each solution block is tagged with word-count markers (e.g., ‘Section A: 500 words’) and includes a plagiarism report via Turnitin (IGNOU-approved).

Note: Deadlines for TMA submission align with the current academic session’s IGNOU calendar (e.g., TMA-01: TBA; TMA-02: TBA).
