GEEResults.conf_int(alpha=0.05, cols=None, cov_type=None)[source]

Returns confidence intervals for the fitted parameters.


alpha : float, optional

The alpha level for the confidence interval. i.e., The default alpha = .05 returns a 95% confidence interval.

cols : array-like, optional

cols specifies which confidence intervals to return

cov_type : string

The covariance type used for computing standard errors; must be one of ‘robust’, ‘naive’, and ‘bias reduced’. See GEE for details.


The confidence interval is based on the Gaussian distribution.
