An Efficient Semiparametric Estimator for Binary Response Models

Factors affecting hospital admission and recovery stay duration of in-patient motor victims in Spain

“…If u is not normally distributed then Newey argues that the semi-parametric estimator provided by Klein and Spady (1993) gives the most efficient estimator, such that where…”

Censored Data and Truncated Distributions

“…The estimator proceeds in two steps. At the first, a robust (semiparametric) estimator of θ in the binary choice model is obtained [Manski' (1985[Manski' ( , 1986[Manski' ( , 1987) maximum score estimator or Klein and Spady's (1993) semiparametric estimator. At the second step, the estimator is weighted least squares using adjacent (both selected) observations, | α− α| increases; the author suggests a kernel function for the weight.…”

Poverty-Sensitive Scorecards to Prioritize Lending and Grant Allocation with an Application in Central America

“…The specific econometric method that we propose for estimating risk scores is the semi-parametric single index model derived by Klein and Spady (1993) because of its relatively faster and less computational burden estimation process, compared to a fully nonparametric method. Recall that we are also looking for a method that can be easily implemented.…”

“…Information from previous loans/grants, including performance and characteristics of the borrowers/grantees, was first gathered from other comparable small enterprises in Latin America. These data served to estimate the parameters of interest using the semi-parametric single index model proposed by Klein and Spady (1993). Finally, the estimated parameters, together with the information provided by the 39 applicants, were used to derive their risk scoring.…”
