The present paper demonstrates that an optimally formulated two-equation model in combination with advanced wall treatment can overcome many problems of previous models. The SST (Shear Stress Transport) WebJul 5, 2011 · SEMs are marked by typically including two or more equations in the model. This process differs from the usual single equation regression model that has a single dependent variable and multiple covariates. In SEMs, it is not unusual to have a number of equations with several explanatory variables in each equation.
