Struct BlockedTimeSeriesCV 

pub struct BlockedTimeSeriesCV { /* private fields */ }

Blocked Time Series Cross-Validation

This cross-validator provides multiple non-contiguous training blocks for time series data, with gap control to prevent data leakage.

Implementations

impl BlockedTimeSeriesCV

pub fn new(n_splits: usize, n_blocks: usize) -> Self

Create a new BlockedTimeSeriesCV cross-validator

pub fn gap(self, gap: usize) -> Self

Set the gap between blocks and test sets

pub fn test_size(self, size: usize) -> Self

Set the size of the test set
