Density Estimation and Random Number Generation with
Distribution Element Trees
Description
Density estimation for possibly large data sets and conditional/unconditional random number generation or bootstrapping with distribution element trees. The function 'det.construct' translates a dataset into a distribution element tree. To evaluate the probability density based on a previously computed tree at arbitrary query points, the function 'det.query' is available. The functions 'det1' and 'det2' provide density estimation and plotting for one- and two-dimensional datasets. Conditional/unconditional smooth bootstrapping from an available distribution element tree can be performed by 'det.rnd'. For more details on distribution element trees, see: Meyer, D.W. (2016) or Meyer, D.W., Statistics and Computing (2017) and Meyer, D.W. (2017) or Meyer, D.W., Journal of Computational and Graphical Statistics (2018) .
