They are a set of modified Western Electric rules, developed by James Westgard and provided in his books and seminars on quality control. [1] They are plotted on Levey–Jennings charts, wherein the X-axis shows each individual sample, and the Y-axis shows how much each one differs from the mean in terms of standard deviation (SD). The rules ...
The Western Electric rules are decision rules in statistical process control for detecting out-of-control or non-random conditions on control charts. [1] Locations of the observations relative to the control chart control limits (typically at ±3 standard deviations) and centerline indicate whether the process in question should be investigated for assignable causes.
[citation needed] One author uses the terminology of the "Rule of Average Conditional Probabilities", [4] while another refers to it as the "continuous law of alternatives" in the continuous case. [5] This result is given by Grimmett and Welsh [6] as the partition theorem, a name that they also give to the related law of total expectation.

The new rules go into effect immediately and were approved by the Division I council last week. The NCAA will no longer limit the amount of times that athletes can transfer schools.
Dühring's plot for boiling point of NaCl solutions [1] Dühring's rule is a scientific rule developed by Eugen Dühring which states that a linear relationship exists between the temperatures at which two solutions exert the same vapour pressure. [1] [2] The rule is often used to compare a pure liquid and a solution at a given concentration.
For example, chemists often choose to look at a small space surrounding the nucleus of an atom: When an electrically neutral atom bonds chemically to another neutral atom that is more electronegative, its electrons are partially drawn away. This leaves the region about that atom's nucleus with a partial positive charge, and it creates a partial ...
(Slow randomness with finite and localized moments) Random draws from a Pareto distribution with mean = 1 and α = 1.5 (Wild randomness) The classification was formally introduced in his 1997 book Fractals and Scaling in Finance , [ 1 ] as a way to bring insight into the three main states of randomness: mild, slow, and wild .
