Forecast analytics calibration survival

Forecast how long each locally calibrated analytical function remains decision-safe using right-censored calibration episodes, a discrete empirical-Bayes failure hazard, conditional survival from current calibration age, posterior uncertainty and explicit endpoint-support gates.

What it's for

Turns model and analytics maintenance from a calendar reminder into an evidence-based forecast of when each deployed capability is likely to need recalibration.

How it works

Sequential Bayesian & bandits — Learn while deciding — update beliefs as evidence arrives and choose where the next unit of effort is worth spending.

  1. 1 Define a governed calibration start, failure event, censoring rule and stable period for every completed or still-surviving function episode, retaining silent retirements as unresolved rather than success.
  2. 2 Construct weighted risk sets and failures by age, shrink sparse function hazards toward the tenant-local pooled hazard, and sample posterior conditional survival from current age through the requested horizon.
  3. 3 Require historical endpoint support and an upper credible failure probability below the governed limit before clearing continued use; otherwise request recalibration or more evidence.

Before you trust it

Every tool in the catalog ships with the conditions under which its answer is meaningful — and the conditions under which it should abstain instead of guessing.

Assumptions & guardrails

  • The likelihood or reward model, prior support, action logging, delayed outcomes, and any stationarity assumptions match the deployment process.
  • Episode starts and failures are comparable and prospectively recorded; censoring is conditionally non-informative; monitoring frequency and calibration-age clock are stable; function versions and regimes are not mixed.
  • Posterior probability and adaptive selection are model-conditional; they are not substitutes for randomized propensities or guaranteed safety.
  • Survival is local to the represented tenant, function family, version and operating epoch; a review flag prioritizes evidence or maintenance and is not proof that any past decision was wrong or authority for automatic suspension.

Minimum evidence

  • calibration_episodes: at least 4 rows/items
  • current_functions: at least 1 rows/items
  • forecast_horizon_periods: required and organization-defined

How to validate it

Use chronological train/calibration/test windows, compare proper scores and decision value with a simple baseline, and recalibrate only from outcomes resolved after prediction time.

Calibrating it to your org

Same for everyone

The mathematical kernel, validation rules, method version, and JSON output semantics are organization-independent; no tenant-trained coefficients or company benchmark is embedded in the function.

Specific to you

  • immutable calibration lifecycle episodes starting at governed activation/recalibration and ending in a prespecified decision-loss failure or right-censoring, preserving version, regime, monitoring cadence and silent retirement
  • calibration/failure/censoring definitions, period and regime, function-family pooling boundary, current age, forecast horizon, prior strength, endpoint support, failure probability, confidence, draws and maintenance authority

Calibration workflow

  1. 1 Define the management decision, target outcome, aggregate unit, privacy boundary, cadence, and prediction/intervention horizon for this organization.
  2. 2 Build a tenant-scoped historical cohort using only information available before each prediction or decision; preserve zero periods, censoring, assignment probabilities, and unresolved outcomes when the method requires them.
  3. 3 Estimate statistical parameters on training history, but obtain costs, utilities, risk tolerance, practical-effect thresholds, capacity, and policy constraints from accountable decision owners.
  4. 4 Validate on later time windows or held-out aggregate units at the deployment grain, against a simple baseline and the function-specific validation strategy.
  5. 5 Deploy only if the returned decision clears evidence, overlap, calibration, robustness, and guardrail checks; warning, unsupported, schema-gap, and fallback decisions are abstentions.
  6. 6 Monitor realized outcomes, data drift, coverage, and decision regret; recalibrate at a governed cadence or after a detected regime/definition change, never merely because a stakeholder dislikes the result.

Call it from your AI

You don't wire up 388 tools in your MCP client. The GitRevio MCP server exposes 18 tools, three of which let an agent search the catalog, read a tool's schema, and run it — so the assistant finds this one on its own.

gitrevio_capabilities_search
  { "q": "forecast how long each locally calibrated" }
  → finds "forecast_analytics_calibration_survival"

gitrevio_capability_describe
  { "capability_id": "forecast_analytics_calibration_survival" }
  → returns the input schema and agent guidance shown on this page

gitrevio_capability_run
  { "capability_id": "forecast_analytics_calibration_survival", "arguments": { ... } }
  → returns the result shown above
