statsmodels.gam.generalized_additive_model.LogitGam.cdf

method

LogitGam.cdf(X)

The logistic cumulative distribution function

Parameters

Xarray-like

X is the linear predictor of the logit model. See notes.

Returns

1/(1 + exp(-X))

Notes

In the logit model,

\[\Lambda\left(x^{\prime}\beta\right)= \text{Prob}\left(Y=1|x\right)= \frac{e^{x^{\prime}\beta}}{1+e^{x^{\prime}\beta}}\]
