I occasionally get a stackoverflow exception in this method.
double norm_cdf(const double x) {
double k = 1.0/(1.0 + 0.2316419*x);
double k_sum = k*(0.319381530 + k*(-0.356563782 + k*(1.781477937 + k*(-1.821255978 + 1.330274429*k))));
if (x >= 0.0) {
return (1.0 - (1.0/(pow(2*M_PI,0.5)))*exp(-0.5*x*x) * k_sum);
} else {
return 1.0 - norm_cdf(-x);
}
}
Any suggestions on why i might be getting it ? Any steps I can take to rectify the error ?
