ci_kurt
(sig=0.05, upper_bound=None, lower_bound=None)[source]¶ Returns the confidence interval for kurtosis.
Parameters: sig : float
The significance level. Default is .05
upper_bound : float
Maximum value of kurtosis the upper limit can be. Default is .99 confidence limit assuming normality.
lower_bound : float
Minimum value of kurtosis the lower limit can be. Default is .99 confidence limit assuming normality.
Returns: Interval : tuple
Lower and upper confidence limit
Notes
For small n, upper_bound and lower_bound may have to be provided by the user. Consider using test_kurt to find values close to the desired significance level.
If function returns f(a) and f(b) must have different signs, consider expanding the bounds.
