Atmosphere, 2022 The potato is the third most consumed crop globally after rice and wheat, but climate change has often disrupted its production. Therefore, adaptation practices are needed to maintain potato productivity.

An ordered probit analysis of transaction stock prices [PDF]
Journal of Financial Economics, 1992 We estimate the conditional distribution of trade-to-trade price changes using ordered probit, a statistical model for discrete random variables. This approach recognizes that transaction price changes occur in discrete increments, typically eighths of a dollar, and occur at irregularly-spaced time intervals.

Driver injury severity: an application of ordered probit models [PDF]
Accident Analysis & Prevention, 2002 This paper describes the use of ordered probit models to examine the risk of different injury levels sustained under all crash types, two-vehicle crashes, and single-vehicle crashes. The results suggest that pickups and sport utility vehicles are less safe than passenger cars under single-vehicle crash conditions. In two-vehicle crashes, however, these

Heliyon, 2020 Most smallholder farmers in sub-Saharan Africa (SSA) are adversely affected by low soil fertility, land degradation and climate change-related shocks such as drought. These problems lead to low productivity and low household income.

Estimation of nested and zero-inflated ordered probit models [PDF]
The Stata Journal: Promoting communications on statistics and Stata, 2018 We introduce three new commands—nop, ziop2, and ziop3—for the estimation of a three-part nested ordered probit model, the two-part zero-inflated ordered probit models of Harris and Zhao (2007, Journal of Econometrics 141: 1073–1099) and Brooks, Harris, and Spencer (2012, Economics Letters 117: 683–686), and a three-part zero-inflated ordered probit ...

Application of Dynamic Spatial Ordered Probit Model [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2009 Although a wide variety of transportation data sets involve discrete values scattered across space and time, there are currently few techniques for properly analyzing such data. This paper describes a new dynamic spatial ordered probit (DSOP) model and demonstrates the model's use in a case of ozone concentration categories.

Journal of Probability and Statistics, 2012 This paper presents a Bayesian analysis of bivariate ordered probit regression model with excess of zeros. Specifically, in the context of joint modeling of two ordered outcomes, we develop zero-inflated bivariate ordered probit model and carry out ...
