[Solved] How to Calculate the sample mean, standard deviation, and variance in C++ from random distributed data and compare with original mean and sigma
There is no standard deviation function C++, so you’d need to do write all the necessary functions yourself — Generate random numbers and calculate the standard deviation. double stDev(const vector<double>& data) { double mean = std::accumulate(data.begin(), data.end(), 0.0) / data.size(); double sqSum = std::inner_product(data.begin(), data.end(), data.begin(), 0.0); return std::sqrt(sqSum / data.size() – mean * mean); … Read more
