# Random Coefficient H-mode Confinement Scalings

@article{Riedel1992RandomCH, title={Random Coefficient H-mode Confinement Scalings}, author={Kurt S. Riedel}, journal={arXiv: Plasma Physics}, year={1992} }

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…
