BACKGROUND Visual acuity measurement often results in an imprecise endpoint because subjects correctly identify some but not all of the letters on one or more size levels on a letter chart. The extent of this transition zone from seeing to nonseeing can be described by probit size, which is calculated by performing Probit Analysis on letter chart data. There has been no previous research into t...

Abstract: This paper investigates the relationship between happiness (utility) and a host of socio-economic variables. The data set consists of a random sample of over 5,000 individuals from the Swedish adult population. Happiness is measured by a three-point categorical measure of overall happiness (not happy, happy sometimes, happy most of the time), and an ordered probit model is used to eco...

This paper investigates immigrant assortative mating and relationship satisfaction. Using a modifi ed random eff ects ordered probit model, the paper demonstrates that spouses of mixed couples are signifi cantly less satisfi ed with their partner than nativeonly and foreign-only couples.

When a responise mlade by a living organism to a stimtultus must fall inlto one or the other of two mutually exclusive classes, it is knowvn as a quantal or all-or-nothing respon...

This paper presents a semi-nonparametric estimator for a series of generalized models that nest the Ordered Probit model and thereby relax the distributional assumptions in that model. It describes a new Stata command for the estimation of such models and presents an illustration of the approach.

Background: The PROBIT methodology was presented in the 1995 World Health Organization Technical Report on Anthropometry as an alternative to the standard prevalence based method of measuring malnutrition in children. Theoretically the PROBIT method will always give a smaller standard error than the standard prevalence method in measuring malnutrition. A recent article by Dale et al. assessed t...
