Algorithms for calculating variance play a major role in computational statistics. A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values. A formula for calculating the variance of an entire population of size N is: Usin
Fast Julia was designed for high performance. Julia programs automatically compile to efficient native code via LLVM, and support multiple platforms. Dynamic Julia is dynamically typed, feels like a scripting language, and has good support for interactive use, but can also optionally be separately compiled. Reproducible Reproducible environments make it possible to recreate the same Julia environm
Probability distributions have a surprising number inter-connections. A dashed line in the chart below indicates an approximate (limit) relationship between two distribution families. A solid line indicates an exact relationship: special case, sum, or transformation. Click on a distribution for the parameterization of that distribution. Click on an arrow for details on the relationship represented
