text of a Ph. D. thesis, "Constructing Confidence Regions for a
Composition of Tectonic Plate Rotations under Heteroscedasticity",

FORTRAN code for constructing the confidence regions described in the thesis:
add2.f composition of two rotations, unequal kappas, using fits from
hellinger1 and all the data for both rotations
addplus.f constructs conservative 95% confidence regions for a composition of
two rotations using only summary statistics, not full data. Valid
if any of the rotations is a triple junction estimate employing a
single kappa but not valid with a triple-junction, unequal-kappas
estimate. Output from addplus can be used by addplus again.
add3.f composition of three rotations, unequal kappas, full data
trikap.f finds a triple junction fit assuming 3 different kappas on the
branches
add2tj.f confidence region construction for combining a triple junction,
single kappa estimate with another rotation having a different kappa,
using all data for both estimates
(minor revision 10 Oct 1999)
addtj4k.f combines a triple junction, 3 kappa estimate with another rotation,
using all data for both estimates
(minor revision 10 Oct 1999)
averotkap.f averages independent estimates of the same rotation, allowing for
unequal kappas, full data
averotplus.f conservative 95% confidence region for the average of independent
estimates of the same rotation, allowing for unequal kappas; uses only
summary statistics provided by hellinger1
hellinger1.f estimates a single tectonic plate rotation
hellinger3.f estimates rotations at triple junctions
invrot.f inverts a rotation using output from hellinger1
addrot.f combines two rotations assuming equal kappas
conreg.f produces a file of points on the boundary of the region of axes in a
rotation confidence region. Uses a rotation fit file from any of the
programs above.
subroutine libraries:
numlib.f
(minor revision 10 Oct 1999)
numlib2.f (LAPACK routines)
dtrans.f
teclib.f
(minor revision 10 Oct 1999)
bingham.f (needed only by conreg.f)
pval.f tests whether a rotation is the Identity
royer2.f combines independent estimates of the same rotation (assumes large
samples or equal kappa's). This program uses a first order approximation
unlike averotkap.f and averotplus.f which use corrections to the first
order approximation.
