Truncated normal hurdle model
text:
In econometrics, the truncated normal hurdle model is a variant of the Tobit model and was first proposed by Cragg in 1971. In a standard Tobit model, represented as y = 1 [ x β + u > 0 ] , where u | x ∼ N This model construction implicitly imposes two first order assumptions: Since: ∂ P [ y > 0 ] / ∂ x j = φ β j / σ and ∂ E [ y ∣ x , y > 0 ] / ∂ x j = β j { 1 − θ ( x β / σ } , the partial effect of x j on the probability P [ y > 0 ] and the conditional expectation: E [ y ∣ x , y > 0 ] has t
