The Markov model showed only slight predictive advantage over the no-change model for short-term forecasting of supermarket choices for a sample of 45 families. While this does not imply a blanket rejection of the Markov technique for forecasting, it is important to recall that this case held to...

In the customer expectations arena, relatively little attention has been paid to the impact on expectations of variation in cultural variables unique to a country. Here the authors focus on one country, India, and a major cultural influence there - the extent of belief in karma. Prior research...

Over the past twenty years, the federal funds rate has evolved from being an intermediate target or indicator variable in discussions of monetary policy to the Federal Reserve’s (exogenous) policy instrument. How the funds rate is characterized has important implications for modeling,...

Consider a simple change-point model with a binary regressor. We examine the consistency of the change-point estimator when the regressor is subject to misclassification. It is found that the time of change can always be identified. Further, special cases where the structural parameters can also...

We perform non-linearity tests using daily data for leading currencies that include the Australian dollar, British pound, Brazilian real, Canadian dollar, euro, Japanese yen, Mexican peso, and the Swiss franc to resolve the issue of whether these currencies are driven by fundamentals or...

In this article, we present two nonparametric trispectrum based tests for testing the hypothesis that an observed time series was generated by what we call a generalized Wiener process (GWP). Assuming the existence of a Weiner process for asset rates of return is critical to the Black- Scholes...
