Block bootstrap time series
WebJul 10, 2015 · I am using the Mann-Kendall test to assess trends in a data time-series. I believe there is autocorrelation in my data and therefore need to use a block bootstrap to correct for it. I have plotted the … WebBlock bootstrapping time series data The usual bootstrapping method doesn't preserve the ordering of time series data, and it is, therefore, unsuitable for trend estimation. In the block bootstrapping approach, we split data into non-overlapping blocks of equal size and use those blocks to generate new samples.
