xin |
A vector of data points - the available sample. |
dist |
Character string, specifies selected distribution function. |
GridLength |
A non-negative number, which will be rounded up if fractional.Desired length of the sequence. |
p1 |
A scalar. Parameter 1 (vector or object) of the selected distribution. |
p2 |
A scalar. Parameter 2 (vector or object) of the selected distribution. |
Implements
η(X)= -0.5 sign(ρ_1)\max|ρ_p + ρ_p^*|
with 1/2 ≤ p ≤ 1.
Uses maximum likehood estimates for the unknown functionals in the definition of the measure.
Returns a scalar, the value of the strong asymmetry measure η(X).
