ECS 4863 ASSIGNMENT 01 DUE DATE: 12 May 2024 UNIQUE NUMBER: . ECONOMETRICS ASSIGNMENT 01 Question 1 1.1The subject deserves to be studied in its own right for the following reasons: Economic theory makes statements or hypotheses that are mostly qualitative in nature (the law of demand), the law does not provide any numerical measures of the relationship. This is the job of the econometrician. The main concern of mathematical Economics is to express economics theory in mathematical for...

INTRODUCTION Dear Student Welcome to MAT2615. We trust that you will find the mathematics studied in this module interesting and useful, and that you will enjoy doing it. THIS TUTORIAL LETTER CONTAINS INFORMATION TO FACILITATE YOUR STUDIES. PLEASE READ IT CAREFULLY AND KEEP IT FOR FUTURE REFERENCE.

The Classical Linear Regression Model (CLRM) correct answers Assumptions: The model is linear in the parameters The explanatory variables X are uncorrelated with the error term The previous assumption leads to E(e|X)=0 The model is correctly specified (i.e. there is no specification bias). This means that we included all relevant variables There is no correlation between two error terms. i.e. cov(ui, uj)=0 u ~ N(0, s2). Homoskedasticity correct answers refers to the assumption that t...

Difference between categorical and quantitative data - ANSWER-Quantitative variables provide numerical information. Categorical variables yield data that can only be considered as categories. Differences in the definitions of a Parameter, Population, Statistic and a Sample - ANSWER-Parameter: Numbers that summarize data from a population Population: Entire collection of a group Statistic: The probability of obtaining a result or numbers that summarize the data from a sample Sample: A man...
