Predicting issuer credit ratings using a semiparametric method

RC Hwang, H Chung, CK Chu - Journal of Empirical Finance, 2010 - Elsevier
This paper proposes a prediction method based on an ordered semiparametric probit model
for credit risk forecast. The proposed prediction model is constructed by replacing the linear …

Predicting bankruptcy using the discrete-time semiparametric hazard model

KF Cheng, CK Chu, RC Hwang - Quantitative Finance, 2010 - Taylor & Francis
The usual bankruptcy prediction models are based on single-period data from firms. These
models ignore the fact that the characteristics of firms change through time, and thus they …

On multiple‐class prediction of issuer credit ratings

RC Hwang, KF Cheng, CF Lee - Applied stochastic Models in …, 2009 - Wiley Online Library
For multiple-class prediction, a frequently used approach is based on ordered probit model.
We show that this approach is not optimal in the sense that it is not designed to minimize the …

A semiparametric method for predicting bankruptcy

RC Hwang, KF Cheng, JC Lee - Journal of Forecasting, 2007 - Wiley Online Library
Bankruptcy prediction methods based on a semiparametric logit model are proposed for
simple random (prospective) and case–control (choice‐based; retrospective) data. The …

Predicting recovery rates using logistic quantile regression with bounded outcomes

JS Siao, RC Hwang, CK Chu - Quantitative Finance, 2016 - Taylor & Francis
Logistic quantile regression (LQR) is used for studying recovery rates. It is developed using
monotone transformations. Using Moody’s Ultimate Recovery Database, we show that the …

A systematic evaluation of the compression and tablet characteristics of various types of microcrystalline cellulose

R Hwang, GR Peck - Pharmaceutical technology, 2001 - elibrary.ru
Presented is a study in which 6 types of MCC that differ in particle size, particle density, and
silicification were systematically evaluated using design of experiments and statistical …

Heterogeneity in the relationship between subjective well-being and its determinants over the life cycle: A varying-coefficient ordered probit approach

YC Lin, RC Hwang, WS Deng - Economic Modelling, 2015 - Elsevier
We examine the evolution of the mechanism behind subjective well-being (SWB) across the
lifespan using data from the 1972–2010 waves of the US General Social Survey. By …

Assessing bankruptcy prediction models via information content of technical inefficiency

RC Hwang, JS Siao, H Chung, CK Chu - Journal of Productivity Analysis, 2011 - Springer
We use a stochastic frontier model with firm-specific technical inefficiency effects in a panel
framework (Battese and Coelli in Empir Econ 20:325–332, 1995 ) to assess two popular …

Forecasting credit ratings with the varying-coefficient model

RC Hwang - Quantitative Finance, 2013 - Taylor & Francis
The dynamic ordered varying-coefficient probit model (DOVPM) is proposed as a model for
studying credit ratings. It is constructed by replacing the constant coefficients of firm-specific …

Predicting recurrent financial distresses with autocorrelation structure: An empirical analysis from an emerging market

RC Hwang, H Chung, JY Ku - Journal of Financial Services Research, 2013 - Springer
The dynamic logit model (DLM) with autocorrelation structure (Liang and Zeger Biometrika
73:13–22, 1986 ) is proposed as a model for predicting recurrent financial distresses. This …
