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
