WebThe value of erf(z) can be found in mathematical tables, as build-in functions in calculators and spread sheets. If you have a programmable calculator, you may find the following … The property erf (−z) = −erf z means that the error function is an odd function. This directly results from the fact that the integrand e is an even function (the antiderivative of an even function which is zero at the origin is an odd function and vice versa). Since the error function is an entire function which … See more In mathematics, the error function (also called the Gauss error function), often denoted by erf, is a complex function of a complex variable defined as: This integral is a See more When the results of a series of measurements are described by a normal distribution with standard deviation σ and expected value 0, then erf (a/σ √2) is the probability that the … See more Complementary error function The complementary error function, denoted erfc, is defined as which also defines … See more Related functions • Gaussian integral, over the whole real line • Gaussian function, derivative See more The name "error function" and its abbreviation erf were proposed by J.
