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

Returns the confidence interval for skewness.

Parameters:	sig (float) – The significance level. Default is .05 upper_bound (float) – Maximum value of skewness the upper limit can be. Default is .99 confidence limit assuming normality. lower_bound (float) – Minimum value of skewness the lower limit can be. Default is .99 confidence level assuming normality.
Returns:	Interval – Confidence interval for the skewness
Return type:	tuple

Notes

If function returns f(a) and f(b) must have different signs, consider expanding lower and upper bounds
