How to Use the Error Function Calculator? 

The procedure to use the error function calculator is as follows:

Step 1: Enter the sample size in the input field

Step 2: Now click the button “Calculate Error Function” to get the result

Step 3: Finally, the error function for the given sample size will be displayed in the output field

What is Meant by Error Function?

In Maths, error function is denoted by erf, which is also known as Gauss error function, is defined as the complex function of the complex variable. It is defined by

\(erf z = \frac{2}{\sqrt{\pi}}\int_{0}^{z}e^{-t^{2}} dt\)

This integral is a sigmoid function that occurs in Statistics, probability, and partial differential equations. The two closely related functions are the complementary error function denoted by “erfc” and the imaginary error function “erfi”.

The complementary error function is defined as:

erfc z = 1- erf z.

The imaginary error function is defined as:

erfi z = -i erf(iz)
