WebExample 58.1 uses boost::accumulators::tag::count, a simple accumulator that counts the number of values passed to it.Thus, since three values are passed, this example writes 3 to standard output. To use an accumulator, you access the class boost::accumulators::accumulator_set, which is a template that expects as its first … Web4. The standard deviation measures how far from the average something is. If you take the standard deviation of the entries of your result vector, you'll get a number that indicates how far each coordinate's standard deviation is from the average of your result vector's coordinates. So for instance, if you result vector were something like v ...
