depth

Data depth concept offers a variety of powerful and user friendly
tools for robust exploration and inference for multivariate data. The offered
techniques may be successfully used in cases of lack of our knowledge on
parametric models generating data due to their nature. The
package consist of among others implementations of several data depth techniques
involving multivariate quantile-quantile plots, multivariate scatter estimators,
multivariate Wilcoxon tests and robust regressions.

depthTukey function

<dl><dt>u</dt>
<dd>Numerical vector or matrix whose depth is to be calculated. Dimension has to be the same as that of the observations.</dd>
<dt>X</dt>
<dd>The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one multivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).</dd>
<dt>ndir</dt>
<dd>number of directions used in computations</dd>
<dt>threads</dt>
<dd>number of threads used in parallel computations. Default value -1 means that all possible cores will be used.</dd>
<dt>exact</dt>
<dd>if TRUE exact alhorithm will be used . Currently it works only for 2 dimensional data set.</dd></dl>

Arguments

Daniel Kosiorowski, Mateusz Bocian, Anna Wegrzynkiewicz and Zygmunt Zawadzki from Cracow University of Economics.
