# Lag time in a logistic function

I would like to ask how it is possible to find a lag time in a logistic function? I have the function: $$x_{\gamma}(k;t)=\frac{1}{1+e^{-k(t-\gamma)}}$$

Thanks a lot!

• can you state the definition of "lag time" – phdmba7of12 Nov 8 at 20:32
• The period when the function is growing slow, before the exponential growth occurs. – Ксения Цочева Nov 8 at 22:37
