Subject:      Re: tphreg with time-varying covariates

Have you considered using the counting process style?  It looks very
promising for two reasons:  1) use of time-varying covariates should not be
in issue while they are in the CLASS statement since no calculations are
needed and 2) the absence of programming statements should make the
processing much more efficient.

HTH,
