erfc

This function is the complementary error function, equal to 1 minus the Gauss error function:

Syntax

erfc(x)

The x argument represents the independent variable and can either be a scalar or a range of numbers. If x is a range, then it must be defined by either using braces { } or by specifying a worksheet column. Any value for x must be real.

Example

If a series of measurements is described by a normal distribution with standard deviation σ and expected value 0, then the probability that the error of a single measurement is less than -.2 or greater than +.2 is given by:

erfc(.2/(2*sqrt(2)) = .920344
