Introduction of the course
in this lecture you will recognize the main assumptions of OLS regression and check the first three assumptions using STATA software
Assumptions of OLS regression.
Checking Linearity.
The error term has a population mean of zero.
Model Specification: omitted variables.
Check the rest of OLS assumptions using STATA
Serial correlation.
Heteroskedasticity.
Multicollinearity.
Normality of the error term
What are structural break models?
Types of a structural break.
How to detect structural breaks?
First: Test with Known Breakpoints
Stationary of Time Series Models (Part 1)
The meaning of Stationary of Time Series
Types of Non-Stationary of Time Series Models
Statistical Tests of Stationarity (unit root test) using STATA:
Augmented Dickey-Fuller (ADF) Test
Phillips-perron test
Vector autoregressive (VAR) model
Choosing optimal lag length in VAR
Stability of the VAR model
Testing for Residual Autocorrelation
Impulse response functions (IRFs)
Example of VAR model using STATA:
Step (1): Check the stationarity of the variables.
Step (2): Determine the lag length in the VAR model.
Step (3): Estimate the VAR model.
Step (4): Check the Stability of the VAR model
Step (5): Testing for Residual Autocorrelation (LM test)
Step (6): The Granger causality test
Step (7): Impulse response functions (IRFs)
