st: Fitting the integral of a unknown function |

Dear statalisters, I am unsure if the topic is 100% related to the objective I am looking for, because I failed to find an exact expression in English. I have two positively correlated variables (say, X and Y) that can range from 0 to 1. For every value of X (0 to 1) I have values for Y, giving a non-linear curve. Is it possible to calculate the area under the curve having only these data? All the best, Tiago * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
