Distance and extinction determination for APOGEE stars with Bayesian method

A Bayesian Method for the Extinction

We propose a Bayesian method to measure the total Galactic extinction parameters, RV and AV . Validation tests based on the simulated data indicate that the method can achieve the accuracy of around 0.01mag. We apply this method to the SDSS BHB stars in the northern Galactic cap and find that the derived extinctions are highly consistent with those from Schlegel et al. (1998). It suggests that ...

A simple Bayesian method of inferring extinction

—Determining whether a species has gone extinct is a central problem in both paleobiology and conservation biology. Past literature has mostly employed equations that yield confidence intervals around the endpoints of temporal ranges. These frequentist methods calculate the chance of not having seen a species lately given that it is still alive (a conditional probability). However, any reasonab...

A Method for Defuzzication by Weighted Distance

A Bayesian method of sample size determination with practical applications

The problem motivating the paper is the determination of sample size in clinical trials under normal likelihoods and at the substantive testing stage of a financial audit where normality is not an appropriate assumption. A combination of analytical and simulation-based techniques within the Bayesian framework is proposed. The framework accommodates two different prior distributions: one is the ...
