Factor affecting outlet choice of onion producers Northwest Ethiopia in multivariate probit approach

Cogent Food & Agriculture, 2020
Onion is an important vegetable product for food security and income generation to a large proportion of the rural household of Ethiopia. Enhancing onion farmers to reach markets and actively engage in the markets as a key challenges influencing onion ...

Simulated Multivariate Random-Effects Probit Models for Unbalanced Panels [PDF]

The Stata Journal: Promoting communications on statistics and Stata, 2014
This article develops a method for implementing a simulated multivariate random-effects probit model for unbalanced panels (with gaps) and illustrates the model by using artificial data. Halton draws generated by mdraws are used to simulate multivariate normal probabilities with the mvnp() egen function.

Bayesian analysis of multivariate nominal measures using multivariate multinomial probit models [PDF]

Computational Statistics & Data Analysis, 2008
The multinomial probit model has emerged as a useful framework for modeling nominal categorical data, but extending such models to multivariate measures presents computational challenges. Following a Bayesian paradigm, we use a Markov chain Monte Carlo (MCMC) method to analyze multivariate nominal measures through multivariate multinomial probit models.

Estimation of Multivariate Probit Models via Bivariate Probit [PDF]

The Stata Journal: Promoting communications on statistics and Stata, 2016
In this article, I suggest the utility of fitting multivariate probit models using a chain of bivariate probit estimators. This approach is based on Stata's biprobit and suest commands and is driven by a Mata function, bvpmvp(). I discuss two potential advantages of the approach over the mvprobit command (Cappellari and Jenkins, 2003, Stata Journal 3 ...

Prospects and constraints in smallholder farmers' adoption of multiple soil carbon enhancing practices in Western Kenya

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.

Marginal effects in multivariate probit models [PDF]

Empirical Economics, 2016
Estimation of marginal or partial effects of covariates x on various conditional parameters or functionals is often a main target of applied microeconometric analysis. In the specific context of probit models, estimation of partial effects involving outcome probabilities will often be of interest. Such estimation is straightforward in univariate models,

Determinants of Market Outlet Choices of Tef Producers in Western Ethiopia: Evidence of Multivariate Probit Model

Turkish Journal of Agriculture: Food Science and Technology, 2022
This study was required to assess the existing tef market outlets and examine factors affecting market outlet choices among smallholder tef producers in western Ethiopia. For this study qualitative and quantitative data were collected from tef producers.
