Reading 12, Types of Errors and Linear Regression

In the previous blogs, heteroskedasticity, serial correlation & multicollinearity were discussed.
These events result in errors as it relates to hypothesis testing. I thought it worthwhile to summarize the types of errors.

Type of violations        Type of Error           Meaning of Error
Heteroskedasticity          Type 1 Error              Rejection of the null hypothesis, when it is true
Serial Correlation            Type 1 Error              Rejection of the null hypothesis, when it is true
Multicollinearity              Type 2 Error              Failure to reject the null hypothesis when it is actually false
