Survival Analysis and Clinical Trials
This course focuses on statistical methods for discrete data collected in public health, clinical and biological studies including survival analysis. This would enable the students to understand the principles of different statistical techniques useful in public health and clinical studies conducted.

Concepts of Time, Order and Random Censoring. Life distributions - Exponential Gamma, Weibull, Lognormal, Pareto, Linear Failure rate. Parametric inference Point estimation, Confidence Intervals, Scores, tests based on LR , MLE
Life tables, Failure rate, mean residual life and their elementary properties. Ageing classes -IFR, IFRA, NBU, NBUE, HNBUE and their duals, Bathtub Failure rate.Estimation of survival function - Actuarial Estimator, Kaplan - Meier Estimator, Estimation under the assumption of IFR/DFR.
Tests of exponentiality against non-parametric classes - Total time on test, Deshpande test. Two sample problem - Gehan Test, Log rank test..Semi-parametric regression for failure rate - Cox's proportional hazards model with one and several covariates.
Clinical trials: introduction, need and ethics , bias and random error, conduct of clinical trials. Overview of phase I-IV trials, multicenter trials. Data management: data definition, case report forms, database design, data collection system
Planning and Design of clinical trials: parallel vs cross over design, cross sectional vs longitudional designs, Phase I, II, and III trials. Consideration in planning a clinical trial,. Analysis of categorical outcomes o Phase I, II, and III trials, analysis of survival data from clinical trials.
