Hierarchical Linear Models of Unit-Level Turnover

	RN Turnover			Nurse's Aide Turnover
	Coeff.	SE	p > |z|	Coeff.	SE	p > |z|
Work environment	−6.78	3.46	.050	−3.01	5.33	.572
Full-time equivalents	−0.03	0.02	.086	0.05	0.19	.797
Constant	24.39	8.94	.006	15.50	13.34	.245
sigma_u	3.19			4.91
sigma_e	4.02			8.59
Rho	0.39			0.25
Number of observations	45			37

As these are unit-level models, the nine hospitals are included as a random effect.
