 | Double |
The DoubleBisquareWeightingFunction type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AdjustedResiduals |
Returns a vector of adjusted residuals for the weighted least
squares problem:
Ax = b.
(Inherited from DoubleLeastSqWeightingFunction) |
| Clone |
Creates a deep copy of this weighting.
(Overrides DoubleLeastSqWeightingFunctionClone) |
| GetWeights |
Computes the bisquare weights for the residuals using the formula:
w(r) = (1 - r^2)^2 if |r| is less than 1 and
w(r) = 0 if |r| is greater or equal to 1.
Here r is the adjusted redisuals from the AdjustedResidual
function of the base class DoubleLeastSqWeightingFunction.
(Overrides DoubleLeastSqWeightingFunctionGetWeights(DoubleVector, DoubleVector)) |
| Initialize |
Performs initialization of the weighting function based on the matrix
A in the weighted least squares problem:
Ax - b.
(Inherited from DoubleLeastSqWeightingFunction) |
| MedianAbsDeviation |
Returns the Mean Absolute Deviation of a vector of values.
The mean absolute deviation is an estimate of the standard
deviation of the vector of residuals normalized to make the
estimate unbiased for the normal distribution.
