  name: Ledger Analytics API
  description: The Ledger Analytics API (operated by Korra, a Ledger Investing company) provides remote compute access to
    Bayesian actuarial models over insurance loss triangles. Triangles are uploaded and managed as first-class resources,
    then development, tail, forecast and cashflow models are fit against them asynchronously and polled as remote tasks, with
    predictions written back as new triangles. Model families include Chain Ladder, Traditional Chain Ladder, ManualATA, MeyersCRC
    and GMCL for loss development; Generalized Bondy, Sherman and Classical Power Transform for tail development; and AR1,
    SSM and Generalized Cape Cod for forecasting. The API is in beta and is consumed primarily through the open-source ledger-analytics
    Python client.
