Objectives
KNOWLEDGE AND ABILITY OF COMPREHENSION
THE COURSE AIMS AT EXAMINING AND GENERALIZING SOME IMPORTANT TOPICS WHICH HAVE BEEN DEALT IN PREVIOUS STATISTICS COURSES-IN PARTICULAR SOME ISSUES OF PROBABILITY THEORY WILL BE REVIEWED AND TECHNIQUES FOR FINDING THE DISTRIBUTION OF A TRANSFORMATION OF RANDOM VARIABLES WILL BE INTRODUCED .
BASIC PRINCIPLES OF STATISTICAL INFERENCE BASED ON THE LIKELIHOOD WILL ALSO BE COVERED
ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING
STATISTICAL TOOLS INTRODUCED IN THE COURSE WILL BE PRESENTED WITH THE PURPOSE TO HIGHLIGHT SOME IMPORTANT THEORETICAL RESULTS AND THEIR POSSIBLE IMPLEMENTATION IN EMPIRICAL CONTEXTS
THE STUDENT WILL BE GIVEN EVIDENCE OF HOW TO SELECT AND USE THE APPROPRIATE STATISTICAL TOOLS AS WELL AS HOW TO INTERPRET AND COMMENT THE RESULTS OF THE ANALYZES PERFORMED.

• JOINT AND CONDITIONAL DISTRIBUTIONS. STOCHASTIC INDEPENDENCE.
• DISTRIBUTIONS OF FUNCTIONS OF RANDOM VARIABLES. EXPECTATIONS OF FUNCTIONS OF RANDOM VARIABLES. CUMULATIVE DISTRIBUTION FUNCTION TECHNIQUE: DISTRIBUTION OF MINIMUM AND MAXIMUM; DISTRIBUTION OF SUM AND DIFFERENCE OF TWO RANDOM VARIABLES; DISTRIBUTION OF PRODUCT AND QUOTIENT. MOMENT GENERATING FUNCTION TECHNIQUE: DISTRIBUTION OF SUMS OF INDEPENDENT RANDOM VARIABLES. THE DISTRIBUTION OF Y=G(X). PROBABILITY INTEGRAL TRANSFORM.

• COMPUTATIONAL PROBLEMS. TESTS BASED ON MAXIMUM LIKELIHOOD (ML RATIO, WALD’S TEST).
Teaching Methods
LECTURES
Verification of learning
THE METHOD OF VERIFICATION OF LEARNING CONSISTS OF A WRITTEN TEST AIMED TO ASSESS THE ABILITY TO USE THE STATISTICAL TECHNIQUES ACQUIRED AND AN ORAL EXAM TO TEST THEIR METHODOLOGICAL IMPLICATIONS.
