This command is using the syntax of -graph- in Stata 7 and earlier.
Stata 8 and 9 have an entirely new -graph- command with all-new syntax.
David can make this command work by using -graph7- rather than -graph-:
. graph7 PrrepyrAL0p0 PrrepyrAL0p1 PrrepyrAL0p2 PrrepyrAL0x, b2("No Loss of Autonomy or No Transfer: POLITY Regime Score") gap(3) l1("Probability") xlabel(-10 -9 to 10) ylabel(0,.25,.50.,.75,1) yscale(0,1) xscale(-10,10) s(OdST) connect(ssss) border
Or, he could set -version 7- before executing the command:
. version 7
. graph PrrepyrAL0p0 PrrepyrAL0p1 PrrepyrAL0p2 PrrepyrAL0x, b2("No Loss of Autonomy or No Transfer: POLITY Regime Score") gap(3) l1("Probability") xlabel(-10 -9 to 10) ylabel(0,.25,.50.,.75,1) yscale(0,1) xscale(-10,10) s(OdST) connect(ssss) border
. (any other commands from the book which need to be run using
version control)
. version 9 (or whatever version David is using)
