Hi, I would like to know if anyone knows how to compute a variance of the non-linear combination of the coefficient estimates.
Say, I get a model of y~c+ax+bz (1) where x and z are the independent variables, c is the constant estimate, and a and b are the coefficient estimates. Then, I want to know the variance of b*c/a (2). How am I going to get it? In Stata, I can just use "bs" function by defining the regression model (1) and the statistic of the interest(2). Help!!!
