  • If provided a value, the accumulator function returns an updated corrected sample skewness. If not provided a value, the accumulator function returns the current corrected sample skewness.
  • If provided NaN or a value which, when used in computations, results in NaN, the accumulated value is NaN for all future invocations.

  Returns accumulator

  accumulator function

  Example

  var accumulator = incrskewness();
  
  var skewness = accumulator();
  // returns null
  
  skewness = accumulator( 2.0 );
  // returns null
  
  skewness = accumulator( -5.0 );
  // returns null
  
  skewness = accumulator( -10.0 );
  // returns ~0.492
  
  skewness = accumulator();
  // returns ~0.492
