statsmodels.emplike.descriptive.DescStatUV.ci_kurt#

DescStatUV.ci_kurt(sig=0.05, upper_bound=None, lower_bound=None)[source]#

Returns the confidence interval for kurtosis

Parameters:

sigfloat, optional: The significance level. Default is .05
upper_boundfloat, optional: Maximum value of kurtosis the upper limit can be. Default is .99 confidence limit assuming normality.
lower_boundfloat, optional: Minimum value of kurtosis the lower limit can be. Default is .99 confidence limit assuming normality.

Returns:

Intervaltuple of float: 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.
