.6%), calcium carbonate (1.2%) and dextrose (3%). The F treatment was inoculated with log5/g fish Lactobacillus. curvatus in sterile peptone water, the C treatment had sterile peptone water as a blank control. Then the two treatments were incubated at 37o...
ENSO and PDO related variability in seasonal range prediction for the Bolivian Altiplano region in South America
(University of Missouri--Columbia, 2019)
This study uses the methodology of some experiences in seasonal range prediction related to El Niño-Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) in North America. Previous studies (e.g Garreaud and Aceituno 2001; Vuille...
Objective Bayesian analysis of the 2 x 2 contingency table and the negative binomial distribution
(University of Missouri--Columbia, 2018)
In Bayesian analysis, the “objective” Bayesian approach seeks to select a prior distribution not by using (often subjective) scientific belief or by mathematical convenience, but rather by deriving it under a pre-specified ...
