For multiple-choice questions, we calculated the absolute number of programs and the percentage of programs that chose each particular answer.
To confirm that this was not merely an artefact of our choice of parameters, we calculated and analyzed the ratio between activation and deactivation time for different parameters.
To determine whether larval choice predicted adult choice, for each treatment we calculated a 'constancy' score, defined as the proportion of individuals choosing ambient air as larvae that also chose ambient air as adults.
To measure how phylotype richness in the four fecal communities varied with sample size and choice of variable region, we calculated rarefaction curves at both 97% and 98% similarity levels (Figure 3).
We calculated choice probability by dividing the responses to the AS image for an individual neuron into two groups of trials based on the choice made with that AS image on that trial.
To evaluate and parameterize the force field of choice we are calculating Gibbs free energy of solvation of a number of alcohols and short poly - ethylene glycol) polymers.
To choose LN[ i], we consider each LN[ j] one at a time for all choices
To further develop on the usability of the star models in comparison between the river- cities and non-river cities in response to cutting the highest choice values, in Table 7 we calculate the absolute distance between values extracted from different star models of river-cities as original values to all other extraction of river-cities including river-cut, river-banks and river-high-cut.
As we expected a higher hybridization probability with decreasing population size (based upon the mate choice experiment), we also calculated a linear regression between effective population size and hybridization rate.
A related but different question is the relationship between trial-by-trial variations in the firing rate of a neuron and the trial-by-trial variations in choices, calculated as choice probabilities (Britten et al., 1996; Parker et al., 2002; Uka & DeAngelis, 2003; Liu & Newsome, 2005; Purushothaman & Bradley, 2005; Uka et al., 2005).
