open suspend override fun composeIntermediate(first: Pair<T, Int>, second: Pair<T, Int>): Pair<T, Int>

open suspend override fun computeIntermediate(data: Buffer<T>): Pair<T, Int>

fun <T, I, R> ComposableStatistic<T, I, R>.flow(flow: Flow<Buffer<T>>, dispatcher: CoroutineDispatcher = Dispatchers.Default): Flow<R>

Perform a streaming statistical analysis on a chunked data. The computation of inner representation is done in parallel if dispatcher allows it.
