WebJan 4, 2024 · Note that sampling without replacement is equivalent to permuting the original observations, so each original observation appears once in the resampled vector. In contrast, sampling with replacement produces a new vector that could contain anywhere from 0 to \(n\) occurrences of each original observation. WebBackward fill the new missing values in the resampled data. Resampler.nearest ([limit]) Resample by using the nearest value. Resampler.fillna (method[, limit]) Fill missing values introduced by upsampling. Resampler.asfreq ([fill_value]) Return the values at the new freq, essentially a reindex.
