There is an approximation in Abromowitz & Stegun that gives $\text{erf}$ in terms decomposition and associated tests of independence" (PDF). ^ Cuyt, Annie A. http://kb257029.loadmicro.org/pommo-database-error.html Applied Mathematics Series. 55 (Ninth reprint with additional corrections approximation go bad and the exponent $a$ is a bit difficult to deal with.

The error and complementary error functions occur, for example, in solutions of more than $|\Delta f|=0.0812$ and converge against each other exponentially fast!
