Without replacement
sample :: (PrimMonad m, Foldable f) => Int -> f a -> Gen (PrimState m) -> m (Maybe [a]) Source #
(O(n)) Sample uniformly, without replacement.
Returns Nothing if the desired sample size is larger than the collection being sampled from.
With replacement
resample :: (PrimMonad m, Foldable f) => Int -> f a -> Gen (PrimState m) -> m [a] Source #
(O(n log n)) Sample uniformly with replacement (bootstrap).
Unequal probability, without replacement
psample :: (PrimMonad m, Foldable f) => Int -> f (Double, a) -> Gen (PrimState m) -> m (Maybe [a]) Source #
(O(n log n)) Unequal probability sampling.
Returns Nothing if the desired sample size is larger than the collection being sampled from.
psampleIO :: Foldable f => Int -> f (Double, a) -> IO (Maybe [a]) Source #
(O(n log n)) psample specialized to IO.
