Thank you, Nick. I tried -rplot-, but twoway line is not allowed. The -eclplot- is defined. How to plot twoway line in -eclplot- command? Thank you for your suggestion.

If you use that, or any other convenient command, to save the coefficients to a dataset, then you can plot the coefficients with -eclplot- (SJ/Roger Newson's own site) or with a suitable combination of -twoway line- and -rcap-. That said, your treatment of years may yield inaccurate confidence intervals if you are not properly modelling serial dependence.

I run an OLS regression regarding returns to education.There are 20 years, each year has its coefficient on returns o education. So, I want to plot a graph, with year on x-axis , each year's coefficient on y-axis, and confidence interval marked on the graph. How to create a data set that store all coefficients in it, so, I can plot this pictureeasily?Maarten, First, thank you for your email regarding the interesting document of -parm- and confidence interval plot. But I see, the plots seems to be in discrete case. If I want to plot graph that is in "twoway line" shape, how to do that? Since I want to plot coefficients over years. I appreciate for your help.

You need to explain precisely what you want, i.e. what is on the y axis, what is on the x axis, and how the 20 coefficients feature.

For example, the model has 20 coefficients, I want to plot the graph regarding these coefficients. I tried to use command -eret-, but coefficients can not be stored in data set. How to do this plotting?
