n.times.eBias {rQCC} | R Documentation |
Empirical biases (times n)
Description
n
times the empirical biases of the median absolute deviation (MAD)
and Shamos estimators.
Usage
n.times.eBias.of.mad
n.times.eBias.of.shamos
Details
n
times the empirical biases of the median absolute deviation (MAD)
and Shamos estimators
under the standard normal distribution, where n
is the sample size
and n
is from 1 to 100.
For the MAD estimator, mad{stats} is used.
For the Shamos estimator, the Fisher-consistent Shamos estimator, shamos
{rQCC}, is used.
These estimators are not unbiased with a finite sample. The empirical biases are obtained using the extensive Monte Carlo simulation with 1E07 replicates.
Value
They return a vector of 100 values.
