Probability and Statistics · Continuous distributions
Uniform, normal and exponential distributions, z-scores, the 68–95–99.7 rule, and computing areas with cdf and ppf.
- For a normal distribution about 68%, 95% and 99.7% of values fall within 1, 2 and 3 standard deviations.
- ppf is the inverse of cdf: it turns a probability back into a value.
