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...

Six Sigma Black Belt Session 8 Questions and Answers Already Passed A Lean Six Sigma team is trying out a new forming tool to reduce variability in a process that creates hamburgers patties in a fast food restaurant. One of the significant dimensions has a process standard deviation of 0.35 mm. The team needs to know how many samples to collect in order to achieve an estimate of the mean with precision of + or - 0.15 mm, with 95% confidence. What sample size is required to meet this goal...

Assumptions of OLS Linearity Assumption: E[Y] = β0 + β1x. We are assuming the expected value of Y for any given X is a linear function of X (approximates to a straight line) 2. Assumption about errors: We assume the error terms are independently and identically distributed (iid) normal random variables with 0 mean and variance σ. 3. Assumptions about predictors: For multiple regression (more than 1 predictor) we assume the predictors are linearly independent. Heteroskedasticity might requi...
