TamboDuc: Basic code lines in Gretl

If you want to run a regression. Using the sample data from Mankiw :

{{ code | ols gdp85 0 gdp60}}

Model 1: OLS, using observations 1-121 (n = 105)
Missing or incomplete observations dropped: 16
Dependent variable: gdp85

coefficient std. error t-ratio p-value

Data from N. Gregory Mankiw, David Romer and David N. Weil,
"A contribution to the empirics of economic growth,"
Quarterly Journal of Economics, May 1992, pp. 407-437

Cross-country data from 1960 and 1985 with average growth
rates of GDP and population of working age, the average
ratio of investment to GDP, and the percentage of the
working-age population in secondary school.

Note by Allin Cottrell:
These data are taken from Appendix to the paper. I believe
they do not correspond exactly to the data used in the
regressions reported in the paper, since I am unable to
reproduce those results exactly (the differences are minor
but noticeable).
