Regression analysis is an that aims to determine whether there a statistically dependent relationship between two variables, namely the predictor variable and response variable. One of methods for estimating multiple linear regression parameters Least Squares Method. Therefore, careful meticulous selection appropriate techniques are required overcome multicollinearity problem ensure accurate me...

There has been a wide debate on whether democracy actually has an effect on economic outcomes, and especially on international trade. With a new estimation strategy, we analyze this relationship taking a look at the distribution of countries’ trading activity. Using a panel quantile estimation framework from Powell (2014), we find a stronger relationship at the lower quantiles, especially for t...

In this note we suggest a new iterative least squares method for estimating scalar and vector ARMA models. A Monte Carlo study shows that the method has better small sample properties than existing least squares methods and compares favourably with maximum likelihood estimation as well.
