Sigma threshold

In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively. In mathematical notation, these facts can be expressed as follows, where Pr() … WebOct 9, 2024 · You can make your own calculation for some good value, and then adjust the range with a sigma around that threshold: lower_bound = (1-sigma)*threshold upper_bound = (1 +sigma)*threshold When sigma, is say, 0.33 - the bounds will be 0.66*threshold and 1.33*threshold, allowing a ~1/3 range around it. Though, finding the threshold is
