Logistic regression of factors associated with future intention to undergo prenatal genetic testing among a sample of university-enrolled students in the U.S. (PGRID study).

Logistic regression		Number of obs = 2,476
		LR χ2(60) = 235.09
		Prob > χ2 = 0.0000
Log likelihood = −1,592.43		Pseudo R2 = 0.0687
Log likelihood (constant-only) = −1,709.97
Correct% classification: 62.3
