  The random coefficient two-stage regression algorithm with the collisional
Maxwell-Vlasov constraint is applied to the ITER H-mode confinement database.
The data violate the collisional Maxwell-Vlasov constraint at the 10-30%
significance level, probably owing to radiation losses. The dimensionally
constrained scaling, $\tau_E = 0.07192 M^{1/2}$ $(R/a)^{-0.221} R^{1.568}
\kappa^{.3} I_p^{.904} B_t^{.201} \bar{n}^{0.106} P^{-0.493}$, is similar to
ITER89P with a slightly stronger size dependence.
