st: Convolution method in stata |

Hi all, I am currently working on a survey in which participants were asked whether they are willing to pay (WTP) $X for either good A or good B. Since good A is inclusive of good B, I am trying to run a scope test in which the null hypothesis is that the mean WTP distribution of the less inclusive good (i.e. good B) is not statistically different from the mean WTP distribution of the more inclusive good (i.e. good A). I am trying to the test this hypothesis by applying the convolution approach in stata and see if this difference is significantly difference from 0 at a 10% confidence level. I was able to compute the 95% confidence intervals for the E(WTP) of each good using the wtpcikr command, but I do not know how to run the convolution method in stata. I would really appreciate if you can help. Thank you! German. ----------------------------- Germán M. Izón Department of Economics PhD.
