From the statistical point of view, if the target phenotype is considered as independent variable and allelic variation in many genome loci as explanatory variables, we need to pick up the variables with significant contribution to the phenotype from tens of thousands of variables. This is so-called variable selection from oversaturated models. There has been many methods to deal with this issue.

Firstly, based on the force acting on a single-particle, establish a discriminant formula of the sand threshold, and prove that the sand threshold belongs to the cusp catastrophe. Then establish the basic equation of the cusp catastrophe using coordinate transformation and catastrophe theory. Finally, while particle Reynold number and equivalend diameter are the state variables and Shields parameter is the control variables, we can obtain the model of cusp catastrophe of sand threshold, putting those variables into the basic equations of the cusp catastrophe. The model is derived from the mathematics, which has a certain mathematical theory foundation.
