hgraph-analytics

C++-first numerical analytics for hgraph. The package owns the numerical analytical family migrated from core—diff, count, clip, ewma, and pct_change—plus the EWMA parameter conversion helpers.

import hgraph as hg
import hgraph_analytics as hga

change = hga.pct_change(
    value,
    period=12,
    divide_by_zero=hg.DivideByZero.NAN,
)

bounded = hga.clip(change, -0.25, 0.25)
smoothed = hga.ewma(bounded, alpha=0.2)

The result is fractional: 0.05 denotes five percent. period counts valid source observations and must be positive. The operator does not infer dataframe ordering, elapsed-time sampling, market sessions, or financial price adjustment.

Native consumers link hgraph::analytics, call hgraph::analytics::register_analytics_operators(), and wire the markers in hgraph::analytics, including diff, count, clip, ewma, and pct_change.

See the hgraph user-guide migration note for the complete Python and C++ name mapping from the former core API.
