Function Calculator Erf(x) Error Function Calculator erf(x) x = Form accepts both decimals and fractions. The error function, denoted erf, is defined by the integral erf(x) = (2/√π)∫xo e-t2 dt. Erf(x) is closely related to the normal probability curve; the cumulative distribution function of a normally distributed random variable X is CDF(X) = 0.5 + 0.5erf[(X-)/σ√2], where is the mean and σ is the standard deviation of the distribution. The error function integral cannot be evaluated in terms of elemetary function, so one must use numerical algorithms. The error function is an odd function whose limit is -1 for negative values of x, and 1 for positive values of x. The function rapidly converges to its asympotic values; erf(3) = 0.99998 and erf(-3) = -0.99998. Properties and Equations The values of x for which x = erf(x) are approximately 0.6175 and -0.6175. If you don't have access to an error function calculator such as the one above, you can approximate the function with the formula The error function can also be expressed with infinite series and continued fractions: You can approximate the inverse of the error function, erf-1(x), by inverting the approximation formula above. The inverse of erf has several interesting derivative and integral properties. © Had2Know 2010 How to Find the Great Circle Distance Between Two Points on a Sphere Gamma & Log Gamma Function Calculator Beta Function Calculator Weibull Distribution Calculator Digamma Function Calculator How to Test Whether Data is Normally Distributed How to Compute Normal Distribution Probabilities How to Read a Z-Score Table to Compute Probability Terms of Use | Privacy Policy | Contact Site Design by E.
