Published in 2020 at "Journal of Earth System Science"

DOI: 10.1007/s12040-020-01483-0

Abstract: Abstract Classical logarithmic linearization of the single backscattering model to estimate the coda Q ( $$ Q_{c} ) $$ Q c ) leads to biased results in the presence of low signal-to-noise ratio. Non-linear regression… read more here.

Published in 2017 at "Journal of the American Statistical Association"

DOI: 10.1080/01621459.2020.1813587

Abstract: Abstract We introduce Bayesian additive regression trees (BART) for log-linear models including multinomial logistic regression and count regression with zero-inflation and overdispersion. BART has been applied to nonparametric mean regression and binary classification problems in… read more here.

Published in 2020 at "Geophysical Journal International"

DOI: 10.1093/gji/ggaa072

Abstract: Bayesian sequential simulation (BSS) is a geostastistical technique, which uses a secondary variable to guide the stochastic simulation of a primary variable. As such, BSS has proven significant promise for the integration of disparate hydrogeophysical… read more here.
