How this service works
QuantOracle: stats/garch-forecast
Output
Returns GARCH model coefficients (omega, alpha, beta), forecasted conditional variance and volatility for each step in the horizon, and confidence intervals around the volatility forecast. May also include model fit statistics such as log-likelihood or AIC.
Example use cases
Example prompt
“Run a GARCH(1,1) volatility forecast on this daily BTC return series [0.02, -0.01, 0.03, ...] and give me the predicted conditional volatility for the next 10 days with 95% confidence intervals.”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/stats/garch-forecastWhen to prefer
Use this endpoint when you need a statistically rigorous conditional volatility forecast based on GARCH modeling, especially for assets exhibiting volatility clustering (e.g., crypto, equities). Prefer this over simple rolling-window volatility when you need forward-looking variance estimates with confidence bounds rather than just historical realized volatility.
Side effects
- Non-stationary or insufficient return series causes model fitting failure
- Invalid GARCH order (p or q = 0 or excessively large) returns parameter error
- Return series too short to estimate parameters reliably
- Convergence failure if series has extreme outliers or near-unit-root behavior
- Missing or malformed input array returns 400 validation error
