The first one introduces a weak dynamical model defined only up to an additional uncertainty time-dependent function whereas the second one, handles a strong dynamical constraint in which the dynamical system's coefficients constitute the control variables.
In other words, the filters of the multi-filter LN model define the only special dimensions of the stimulus space; for all other, orthogonal stimulus dimensions, the original symmetry of the stimulus distribution is preserved, and the stimulus variance stays constant.
These models also define only a small number of routes through which drugs flow.
Most models defined not only an initial frequency of the resistance allele but also set this frequency to a value several orders of magnitude above the frequency predicted under the hypothesis of mutation selection balance.
To determine whether WFDC6 was under different selective constraints in chimpanzees, we performed two more tests: a three-ratio model, where we define the human and chimpanzee and their ancestor as one clade, and another three-ratio model, where we define only the chimpanzee WFDC6 as an independent clade.
The main difference between the preceding models and the switching regression model is that in the case of the switching regression model the distributions of the components error terms are defined on the whole population while in the case of the mixture models they are defined only on the corresponding sub-populations (Maddala 1999).
To the best of our knowledge, the only security model defined in literature for PEKS against KGA is by Rhee et al. [11].
A final sensitivity analysis, for the indicator model, defined alcohol use for moderate drinkers only (>1 drink/day) in accordance with the 2010 Dietary Guidelines for Americans [ 23].
As previously discussed, the simplified model invites the user to define only three parameters (installed capacity, drilling depth, and number of wells).
In some cases, models for predicting the presence or absence of a species in an area are less complex and require less data than an HQI model because one can simply define only two categories on the landscape: areas that provide habitat and areas that do not.
