Q1 : What is Stata?
A1 : Stata is a data analysis software similar to EViews, SPSS, and R. Stata combines the point-and-click approach (like in EViews & SPSS) and programming technique (like in R) to running data analysis, hence giving the users the flexibility they need depending on their level of competencies.

Q2 : What is OLS?
A2 : OLS is an acronym for Ordinary Least Square regression, the most common technique for estimating a linear relationship between one or more independent variables and a dependent variable.

Q3 : What are the CLRM assumptions?
A3 : The Classical Linear Regression Model (CLRM) assumptions outline several requirements for the OLS estimation to fulfill so that its estimator can be the Best Linear Unbiased Estimator (BLUE). Violations of the assumptions may lead to several problems such as heteroskedasticity, serial correlation, model misspecification, omitted variable bias, the presence of outliers or non-normality in residuals.

Q4 : What is Do file
A4 : Do file is considered one of the important features in Stata where Stata users can write down notes and commands in planning their analytical work and the flow of their analysis. From the Do file, users can simply execute the commands of their interests either selected commands or the whole commands listed in the Do file.
