Struct RandomIidSplit 

pub struct RandomIidSplit {
    pub rows: RowSplit,
    pub seed: u64,
    pub test_frac: OrderedFrac,
}

Random IID train/test split (seeded; metadata only).

Fields

rows: RowSplit

Resulting row partition.

seed: u64

Seed used to shuffle.

test_frac: OrderedFrac

Requested test fraction.

Implementations

impl RandomIidSplit

pub fn try_new(n: usize, test_frac: f64, seed: u64) -> Result<Self, DataError>

Shuffle 0..n and take the last test_frac as test.

For temporal / panel / event data, callers must pass TemporalRandomPolicy::Allow via ensure_random_allowed_on_temporal before constructing this split.

Errors

Empty n, invalid fraction, or empty train/test after rounding.
