The next direction is determined using a general deviation rate estimated from the observed deviation a chimpanzee follows between the direction adopted to reach a resource and the direction selected when he leaves the resource.
Here we substantially extend Fisher's model, by allowing a wider class of mutational distributions that incorporate mutational bias and more general deviations from spherical symmetry such as correlations between mutant effects.
In general, deviations from classical models are not consistent for any individual from one task to the next or between individuals for the same task.
However, in general, deviations were rather small.
In general, RPE shows the percentage deviation between the calculated values from the Weibull distribution and the calculated values from measured data.
In general indoor and mine environments, the deviation between the deposition fractions of attached aerosol on the wire screens designed in this study and its reference values in the respiratory tract is less than 5%.
Column leaching test show a good reproducibility (deviation between replicates in general <20 %) and robustness [44].
For values attached to hypothetical health states, no general pattern could be detected that shows deviation between healthy people and ill people.
The popular TTO technique adopted from the field of health economics reveals far more deviation between patients and the general population.
When able to compare certain specifications with one another, there is considerable deviation between efficiency rankings across specifications; in general, there is only a mildly positive correlation between specification efficiency rankings.
