The liability-threshold model is a threshold model of categorical ... Gianola 1982, "Theory and analysis of threshold characters" McGue; et al. (1983).
The model is sometimes referred to as the Rating Scale Model when (i) items have the same number of thresholds and (ii) in turn, the difference between any given threshold location and the mean of the threshold locations is equal or uniform across items. This is, however, a potentially misleading name for the model because it is far more ...
Most proofs of coexistence for threshold voter models are based on comparisons with hybrid model known as the threshold contact process with parameter >. This is the process on [ 0 , 1 ] Z d {\displaystyle \scriptstyle [0,1]^{Z^{d}}} with flip rates:
The point at which critical mass is achieved is sometimes referred to as a threshold within the threshold model of statistical modeling. The term "critical mass" is borrowed from nuclear physics, where it refers to the amount of a substance needed to sustain a chain reaction. Within social sciences, critical mass has its roots in sociology and ...
J. A. Sved [9] showed that a threshold model of selection, where individuals with a phenotype less than the threshold die and individuals with a phenotype above the threshold are all equally fit, allows for a greater substitution rate than Haldane's model (though no obvious upper limit was found, though tentative paths to calculate one were ...
SETAR models were introduced by Howell Tong in 1977 and more fully developed in the seminal paper (Tong and Lim, 1980). They can be thought of in terms of extension of autoregressive models, allowing for changes in the model parameters according to the value of weakly exogenous threshold variable z t, assumed to be past values of y, e.g. y t-d, where d is the delay parameter, triggering the ...
The linear no-threshold model (LNT) is a dose-response model used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The model assumes a linear relationship between dose and health effects, even for ...
The multifactorial threshold model [3] assumes that gene defects for multifactorial traits are usually distributed within populations. Firstly, different populations might have different thresholds. Firstly, different populations might have different thresholds.
