    # A dataset containing a tibble with time series samples
    # for the Mato Grosso state in Brasil
    # create a list to store the results
    results <- list()

    # accuracy assessment lightTAE
    acc_ltae <- sits_kfold_validate(samples_modis_ndvi,
        folds = 5,
        multicores = 1,
        ml_method = sits_lighttae()
    )
    # use a name
    acc_ltae$name <- "LightTAE"

    # put the result in a list
    results[[length(results) + 1]] <- acc_ltae

    # save to xlsx file
