Subject   st: graphing predicted probabilities and confidence intervals with 'praccum'

Hi all, I wanted to graph the predicted probabilities and confidence intervals of one of the outcomes in a multinomial model with two interactions.

My problem is that I do not know how to save the CI's using 'praccum' and to produce the graph.

Is it possible to do it?


Find below the sintax

mlogit orga anac a10 ideol01 in1 in2 in4 in5 ideol0110 in110 in210 in410 in510 [pweight=p1002] if a1002==1, vce(cluster ccaa) base(1)

forvalues count = 0(.1) 1 {
       quietly prvalue, x(a10=0 ideol0110=0 in110=0 in210=0 in410=0 in510=0 ideol01=`count') rest(mean)
       praccum, using(m_2002) xis(`count') ci
praccum, using(m_2002) gen(p2002)

forvalues count = 0(.1)1 {
       quietly prvalue, x(a10=1 ideol0110=`count' ideol01=`count') rest(mean)
       praccum, using(m_2010) xis(`count')
praccum, using(m_2010) gen(p2010)
