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.
