zepid.calc.utils.sensitivity

zepid.calc.utils.sensitivity(detected, cases, alpha=0.05, confint='wald')

Calculate the sensitivity from number of detected cases and the number of total true cases.

Parameters:

• detected (integer, float) – Number of true cases detected via testing criteria
• cases (integer, float) – Total number of true/actual cases
• alpha (float, optional) – Alpha value to calculate two-sided Wald confidence intervals. Default is 95% confidence interval
• confint (string, optional) – Type of confidence interval to generate. Current options include Wald or Hypergeometric confidence intervals

Returns:

Tuple of sensitivity, lower CL, upper CL, SE

Return type:

tuple

Examples

Calculating sensitivity

>>> from zepid.calc import sensitivity
>>> se = sensitivity(90, 100)

Extract sensitivity

>>> se[0]

Extract confidence intervals for sensitivity

>>> se[1:3]

Extract standard error

>>> se[3]
