In the "symmetrical rates" model three parameters were estimated, which represent the symmetrical transition rates between all three states non-migratory, short-distance migration, and long-distance migration.
In alpha-factor model, two parameters Q T and α k are predefined.
For the fractal geometric model, two parameters(D and G) are introduced to describe roughness characteristics.
In addition to regression parameter in this model, two parameters of the random effects were estimated.
We set M equal to 50 for the standard model (one parameter) and 100 for the alternative models (two parameters).
There were n = 2555 data points, 365 days of case data for each of seven years, and k, the number of parameters estimated was 28 in the full model (four parameters for seven years) and 16 in each other model (two parameters for seven years and two parameters overall).
Moreover, on multiple Cox regression models, two parameters of axillary involvement were indicative of outcome: the presence of more than three involved lymph nodes and extracapsular spread.
In the general model, two parameters, C and S, of the inverse S-function are adjustable and can be tuned for different transcription factors in a specific cell.
As in a regular threshold model, two parameters have to be set fixed (e.g. threshold and the residual variance are set to zero and one, respectively) since these parameters are not identifiable in a liability model.
For instance, in the case of porous material with rigid frame, and according to the Champoux Allard model, five parameters are employed.
After approximating this function by a second-order model, three parameters of this reduced structure captured the essential features of the original process.
