utils_block_size

Default Block Size for Restricted Permutation in Dissimilarity Analyses

Fast C++ implementation of Dynamic Time Warping for time series dissimilarity analysis, with applications in environmental monitoring and sensor data analysis, climate science, signal processing and pattern recognition, and financial data analysis. Built upon the ideas presented in Benito and Birks (2020) <doi:10.1111/ecog.04895>, provides tools for analyzing time series of varying lengths and structures, including irregular multivariate time series. Key features include individual variable contribution analysis, restricted permutation tests for statistical significance, and imputation of missing data via GAMs. Additionally, the package provides an ample set of tools to prepare and manage time series data.

utils_block_size function

<dl><dt>tsl</dt>
<dd>(required, list) Time series list. Default: NULL</dd>
<dt>block_size</dt>
<dd>(optional, integer vector) Row block sizes for restricted permutation tests. Only relevant when permutation methods are "restricted" or "restricted_by_row". A block of size <code>n</code> indicates that a row can only be permuted within a block of <code>n</code> adjacent rows. If NULL, defaults to the 20% rows of the shortest time series in <code>tsl</code>. Minimum value is 2, and maximum value is 50% rows of the shortest time series in <code>tsl</code>. Default: NULL.</dd></dl>
