Hello!
I am running ordered probit regression and I need some help with the
interpretation of the coefficients. The dependent variable has 4
categories. A few of the independent var-s are level. One is ln(GDP
per capita). I also have 3 categorical independent variables,
converted to dummies. So my question is, how to interpret the effect
on ln(GDP per capita) on y*. And how to do the same for the dummies?
Here is the part of the raw and standardized coefficients that bothers
me:

Y* |                             b         z     P>|z|    bStdX
bStdY   bStdXY      SDofX
-------------+----------------------------------------------------------------
 logGDPcapita | -65.14180   -3.618   0.000   -5.3093  -59.5872
