![General Logistic Function](https://wikimedia.org/api/rest_v1/media/math/render/svg/25076dc2b208b66357ea02b249c2da195d352fcc)

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.
