Hi, Is there a quick way using Zelig to simulate first differences as a variable is increased multiple times in increments of 1 unit? Viral

Hi Viral & everyone else, Borrowing the code from the top of page 32 of the Zelig manual seems to work well for this: p1b.nocon <- setx(p1a, contact = 0) p1b.con <- setx(p1a, contact = 1) s.out <-sim(p1a, x=p1b.nocon, x1 = p1b.con) summary(s.out) #optionally, the graphs are also really cool, although 1b doesn't ask for them: plot(s.out) Have a great weekend, Ariel Ariel Dora Stern ariel.d.stern at gmail.com ____________________________________ c/o PhD Mailboxes | Harvard Kennedy School 79 JFK Street | Cambridge, MA | 02138 | USA +1 (646) 400 4845 | +49 (0) 178 153 8289 On Fri, Apr 2, 2010 at 3:47 PM, Viral Gandhi < viral_gandhi at hksphd.harvard.edu> wrote:

I'm was thinking about 1.d where we calculate first differences as we raise education from 1 to 7. Is the only way to do this to calculate 6 first differences separately? On 2 April 2010 17:52, Ariel Dora Stern <ariel.d.stern at gmail.com> wrote:

I think we just have to do 2: one for educ = 1 & one for educ = 7; or are others doing this differently? On Fri, Apr 2, 2010 at 6:40 PM, Viral Gandhi < viral_gandhi at hksphd.harvard.edu> wrote:
