This article examines, what makes rural household a preferred choice for formal lenders? It develops sample selected ordered probit model to address this question. While, the selection equation models the determinants of access to credit, an ordered probit model is used to determine the factors...

In this paper we consider modeling leptokurtic daily log-return distributions of three commodities: gold, silver and crude oil. Three modeling approaches are tried out namely (a) a two component mixture of normal distributions model, (b) Variance Gamma (VG) distribution model and (c) Generalized...

The well known Shewharts control chart for mean is constructed under the assumption that the distribution of underlying quality characteristic is normal. It is known that the performance of this control chart is seriously degraded if the underlying distribution is different from normal. Since in...

In this paper we introduce a new likelihood based method, called the likelihood integrated method, which is distinct from the well known integrated likelihood method. We use the likelihood integrated to propose a simple exploratory graphical analysis for the change point problem in the context...

In this paper we discuss a simple fully Bayesian analysis of the change point problem for the directional data in the parametric framework with circular normal distribution as the underlying distribution. We discuss the problem of detecting change in the mean direction of the circular normal...

In this paper we propose two new methods of portfolio allocation which are applicable for all return distributions. The properties of these new methods are compared with that of Markowitzs mean-variance method using extensive simulation. It is found that the new methods perform appreciably in...

Rank data occurs quite regularly in the context of market research studies, opinion polls, sports, etc. In this paper, we discuss the problem of estimation of the true rank when the rank given by the respondents are subject to error. Various error structures are discussed like, transposition...

Control charts play a very important role in the control of manufacturing processes. In this paper we consider the commonly used performance measures for control charts and study their SB-robustness. It is shown that the False Alarm Probability, Average Sample Number (ASN) when the process is...

In this paper, we analyze the price movements of the Indian domestic airline industry. In the first part, we conduct a detailed econometric analysis of five selected domestic routes. In the second part, we study the weekend effect on the average airfare. Our research suggests that competition...
