A new evaluation protocol for detrital zircon: BAD-ZUPA

Bayesian Approach for Detrital Zircon U–Pb ages (BAD-ZUPA) is a new evaluation protocol and based on computer algorithm Riihimaki and Vehtari (2014)'s Laplace approximation with logistic Gaussian process regression (LA-LGP). BAD-ZUPA provides confidence intervals for detrital zircon spectra (PDF) and its cumulative distribution (CDF). In addition it automatically detect peaks and valleys in the spectra with their respective 95% confidence interval in age and their significance level.
