A sample path of compound Poisson risk process. The theoretical foundation of ruin theory, known as the Cramér–Lundberg model (or classical compound-Poisson risk model, classical risk process [2] or Poisson risk process) was introduced in 1903 by the Swedish actuary Filip Lundberg. [3] Lundberg's work was republished in the 1930s by Harald ...
In it, geometrical shapes can be made, as well as expressions from the normal graphing calculator, with extra features. [8] In September 2023, Desmos released a beta for a 3D calculator, which added features on top of the 2D calculator, including cross products, partial derivatives and double-variable parametric equations.

Free Calculator: Online and downloadable scripts (Python and Lua) for Atkinson, Gini, and Hoover inequalities; Users of the R data analysis software can install the "ineq" package which allows for computation of a variety of inequality indices including Gini, Atkinson, Theil.
The Casio Algebra FX series was a line of graphing calculators manufactured by Japanese electronics company Casio Computer Co., Ltd from 1999 to 2003. They were the successor models to the CFX-9970G, the first Casio calculator with computer algebra system, or CAS, a program for symbolic manipulation of mathematical expressions.
In additive combinatorics, the Plünnecke–Ruzsa inequality is an inequality that bounds the size of various sumsets of a set , given that there is another set so that + is not much larger than . A slightly weaker version of this inequality was originally proven and published by Helmut Plünnecke (1970). [ 1 ]
Bennett's inequality, an upper bound on the probability that the sum of independent random variables deviates from its expected value by more than any specified amount Bhatia–Davis inequality , an upper bound on the variance of any bounded probability distribution
The Theil index is a statistic primarily used to measure economic inequality [1] and other economic phenomena, though it has also been used to measure racial segregation. [2] [3] The Theil index T T is the same as redundancy in information theory which is the maximum possible entropy of the data minus the observed entropy.
These variables are also shared by other functions of the calculator, for instance, drawing a graph will overwrite the X and Y values. MicroPython was added to Casio graphing from the PRIZM fx-CG50 and the fx-9860 GIII series. The latest Classwiz CG Series of graphing calculators instead use the Python programming language. [12]
