question about gaussian_kern() parameters?

hi, hope all is well with you!  we are reviewing some functions in our `library(convey)` to make sure our mathematics is sound and we're trying to reconcile why some of our at risk of poverty rate calculations are yielding very tiny differences from `library(vardpoor)` ..  we have looked over the calculations in Osier's 2009 paper and we're curious if you might take a look at how `linarpr` implements the equation under section 2.2 on page 182 of the PDF below?  the equation below _By using the derivation rule (33), we obtain_ includes the threshold `x=ARPT (M)` but from our reading of `linarpr`, we're not sure if you're using `x=MED (M)` in this position instead?  we've presented this as a pull request just to make it easier to highlight our question about the implementation but we definitely might be making a mistake or mis-reading the math on our end.  we appreciate your time with this!  -anthony and @guilhermejacob
