sumOfSquaredDeviation property

  1. @TagNumber.new(3)
double get sumOfSquaredDeviation

The sum of squared deviations from the mean of the values in the population. For values x_i this is:

Sum[i=1..n]((x_i - mean)^2)

Knuth, "The Art of Computer Programming", Vol. 2, page 323, 3rd edition describes Welford's method for accumulating this sum in one pass.

If count is zero then this field must be zero.

Implementation

@$pb.TagNumber(3)
$core.double get sumOfSquaredDeviation => $_getN(2);
  1. @TagNumber.new(3)
set sumOfSquaredDeviation (double value)

Implementation

@$pb.TagNumber(3)
set sumOfSquaredDeviation($core.double value) => $_setDouble(2, value);
