Approximation of the NTCP Function in the LKB Model
Equation
The integral of the Gaussian can be approximated by the expression
| $\displaystyle\frac{1}{\sqrt{2\pi}}\displaystyle\int_{-\infty}^t du\,e^{-u^2/2}=\displaystyle\frac{1}{1+e^{-0.07056 t^3 - .5976 t}}$ |
so it is necessary that in the first approximation the NTCP is:
| $NTCP=\displaystyle\frac{1}{1+e^{-1.5976t-0.07056t^3}}$ |
