Background In 2015, new disability weights (DWs) for infectious diseases were constructed based on data from four European countries. In this paper, we evaluated if country, age, sex, disease experience status, income and educational levels have an impact on these DWs. Methods We analyzed paired comparison responses of the European DW study by participants' characteristics with separate probi...

Dynamic latent factors estimated from panels of macroeconomic indicators are used to predict future NBER recession dates. Three monthly macro factors are considered: (1) a bond and exchange rates factor extracted from 22 financial time series; (2) a stock market factor extracted from 4 stock market indicators; (3) a real factor extracted from 4 macroeconomic time series. Three main results emer...

This document provides supplementary material to our paper “Gender, Competitiveness and Career Choices”. Appendix I presents tables with additional results. This includes descriptive statistics of the control variables (A.I), a comparison of study tracks by gender in the national statistics and in our sample (A.II), the distribution of undergraduate major students by study track at the pre-univ...

This note points out to applied researchers what adjustments are needed to the coefficient estimates in a random effects probit model in order to make valid comparisons in terms of coefficient estimates and marginal effects across different specifications. These adjustments are necessary because of the normalisation that is used by standard software in order to facilitate easy estimation of the...

Probit residuals need not sum to zero in general. However, if explanatory variables are qualitative the sum can be shown to be zero for many models. Indeed this remains true for binary dependent variable models other than Probit and Logit. Even if some explanatory variables are quantitative, residuals can sum to almost zero more often than might at first seem plausible.

INTRODUCTION The assessment of the prevalence of acute malnutrition in children under five is widely used for the detection of emergencies, planning interventions, advocacy, and monitoring and evaluation. This study examined PROBIT Methods which convert parameters (mean and standard deviation (SD)) of a normally distributed variable to a cumulative probability below any cut-off to estimate acut...

This paper examines the contributing factors to the increase in the numbers of divorced and separated mothers in Taiwan since the end of 1980s. In particular, it tests the hypothesis of women’s economic independence. Data from the Survey of Family Income and Expenditures is used; women’s potential earnings are used as the measure of their economic independence. A probit model is employed to exa...
