skbio.stats.power.confidence_bound(vec, alpha=0.05, df=None, axis=None)[source]

Calculates a confidence bound assuming a normal distribution

State: Experimental as of 0.4.0.

Parameters:
  • vec (array_like) – The array of values to use in the bound calculation.
  • alpha (float, optional) – The critical value, used for the confidence bound calculation.
  • df (float, optional) – The degrees of freedom associated with the distribution. If None is given, df is assumed to be the number of elements in specified axis.
  • axis (positive int, optional) – The axis over which to take the deviation. When axis is None, a single value will be calculated for the whole matrix.
Returns:

bound – The confidence bound around the mean. The confidence interval is [mean - bound, mean + bound].
Return type:

float
