Nyquist Frequency in Sequentially Sampled Data

Faghih, Nezameddin; Faghih, Ali - 2008

This paper studies the sequential sampling scheme as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value. Sequential sampling is analyzed and it is proved that when the sampling ratio is an integral number, the associated spectral...

A Bayesian Model of Sample Selection with a Discrete Outcome Variable

Maksym, Obrizan - 2010

Relatively few published studies apply Heckman’s (1979) sample selection model to the case of a discrete endogenous variable and those are limited to a single outcome equation. However, there are potentially many applications for this model in health, labor and financial economics. To fill in...

The Effects of Detailing on Prescribing Decisions under Quality Uncertainty

Ching, Andrew; Ishihara, Masakazu - 2007

We develop a structural model of detailing and prescribing decisions under an environment where detailing helps physicians obtain the current information sets about drug qualities. Our model assumes that a representative opinion leader is responsible for updating the prior belief about the...
