But Big Oil was also operating according to a business model that assumed an ever-increasing demand for its products, however costly they might be to produce and refine.
"The government first came out with their flow rate estimate of around 5 million barrels on August 2, 2010 after a few hours of work," based on a model that assumed the well geometry had not changed in 85 days, Brock said.
This effect was reproduced in a computational energy-minimization model that assumed no microtubule dynamics, but only a taxol-induced increase in the length of the microtubules.
A total of 51,385 SNPs were jointly fitted using Bayesian techniques as random effects in a mixture model that assumed a known large proportion (99.5%) of SNPs had zero effect.
Leaf decomposition k-values were computed using an exponential decay model that assumed the rate of loss from leaf packs was a constant proportion over time.
Heckman [ 13, 14] extended the Tobit model to a two-part model referred to as the sample selection model that assumed an underlying bivariate normal error.
We set five discrete rate categories for the Γ-distribution and used a codon model that assumed a single value of d N / d S for all branches in the tree.
In fact the smallest AIC (510.0) came from the analysis that applied our imputed values to a model that assumed fixed mine-specific intercepts and a fixed common slope.
These heritability estimates were obtained with a model that assumed each line is a random sample from the reference population of global maize inbreds, modeled by a genotypic variance-covariance structure equal to the genotypic variance component multiplied by an identity matrix.
For each of the seven clades, the declining model fit well with the provided data while the model that assumed a constant rate of diversifaction did not.
