The parameters of the logit model.
- Returns:¶
- loglike
float
The log-likelihood function of the model evaluated at params. See notes.
- loglike
Notes
\[\ln L=\sum_{i}\ln\Lambda \left(q_{i}x_{i}^{\prime}\beta\right)\]Where \(q=2y-1\). This simplification comes from the fact that the logistic distribution is symmetric.
