Intuitive Parameters from above. \
$$A$$: Lowest value for the graph, basically the lower asymptote.\
$$K$$: Upper Asymptote\
$$B$$: It's the steepness of the curve in the linear region. \
$$C,Q, v$$:Mostly take them to be 1.&#x20;

You can get the **sigmoid function** form above with the following values:

$$A$$= 0 and all other parameters to be 1.
