Time Series Resampling Sets and Plans

These resampling tools are exported from the timetk package.

• timetk::time_series_cv(): Creates resample sets using time series cross validation

• timetk::time_series_split(): Makes an initial time series split

• timetk::plot_time_series_cv_plan(): Plots a cross validation plan

• timetk::tk_time_series_cv_plan(): Unnests a cross validation plan

Examples

# Generate Time Series Resamples
resamples_tscv <- time_series_cv(
    data        = m750,
    assess      = "2 years",
    initial     = "5 years",
    skip        = "2 years",
    slice_limit = 4
)
#> Using date_var: date

resamples_tscv
#> # Time Series Cross Validation Plan 
#> # A tibble: 4 × 2
#>   splits          id    
#>   <list>          <chr> 
#> 1 <split [60/24]> Slice1
#> 2 <split [60/24]> Slice2
#> 3 <split [60/24]> Slice3
#> 4 <split [60/24]> Slice4

# Visualize the Resample Sets
resamples_tscv %>%
    tk_time_series_cv_plan() %>%
    plot_time_series_cv_plan(
        date, value,
        .facet_ncol  = 2,
        .interactive = FALSE
    )
