Hello!

I'm trying to produce something similar to the figure 3 of Beck, Levine, and Levkov (2010). Unlike the paper has 10 pre periods and 15 post periods, I have 3 pre periods and 2 post periods. I wonder how this part of the code can be revised to reflect I have 3 pre and 2 post periods?

matrix M = r(table)
scalar x = 0
forvalues i = -10(1)15 {
    if `i' != 0 {
        local j = cond(`i' < 0, `i'+11, `i'+10)
        replace b = M[1, `j'] if _tintra == `i'
        replace LB = M[5, `j'] if _tintra == `i'
        replace UB = M[6, `j'] if _tintra == `i'
    }
    if `i' < 0 {
        scalar x = x + M[1, `j']
    }
}
scalar x = x/10

So for i = -10(1)15 I shall change it to i = -3(1)2, what about the part below?

        local j = cond(`i' < 0, `i'+11, `i'+10)
        replace b = M[1, `j'] if _tintra == `i'
        replace LB = M[5, `j'] if _tintra == `i'
        replace UB = M[6, `j'] if _tintra == `i'

As for scalar x = x/10, I suppose I need to change it to 3, as I have 3 pre periods.


Thanks a lot,
