Dear Stata-Listers,
I have to perform some correspondence analyses and did therefore download
the mca.ado and coranal.ado of Philippe Van Kerm (University of Namur, BE)
from stata.com.
Unfortunately both ados always produce an error r(198) "operator invalid"
after the output of the principal inertia components.
Obviously there is something wrong in the ado file itself. Is it possible
that I experience a version incompatibility here (the ados were written for
version 5 - I, myself, use 8.2)?
Did anyone experience the same problem and found a solution/workaround?
Here the example from the help files for -mca- and the output I get:
. sysuse auto
(1978 Automobile Data)
. mca foreign rep78 headroom, d(3)

Help is as always very much appreciated!
