Q
When you scale data (e.g. take logs) what happens to the slope coefficient?
A
Nothing it isnt effected by scaling
2
Q
What test do we perform if we are looking at Linear Function Form?
A
- Ramsey Reset Test
Consequence of Failure
- Coefficient Estimates biased
3
Q
What test do we perform if we are looking at Errors being serially independent?
A
- Durbin-Watson Test
- Durbin’s h-test
- Breusch-Godfrey
Consequences of Failure
- Estimates are unbiased but inefficient
- The standard errors of the coefficients are biased
4
Q
What test do we perform if we are looking at Errors having constant variance?
A
- White test
- ARCH test
- Goldfeld-Quandt test
Consequency of Failure
- Estimates are unbiased but inefficient
- The standard errros of the coefficients are biase
5
Q
What test do we perform when looking at Errors being Normally Distributed?
A
- Jarque-Bera test
Consequences of Failure
- Estimates are unbiased
- Distribution of estimates unknown

Q
What is the Jarque-Bera test?
A
- Gamma 1 - Skewness formula
- Gamma 2 - Kurosis formula
- follows a Chi-squared distribution with 2 degrees of freedom
