The package provides analytical European option prices, Monte Carlo pricing with antithetic and control variates, confidence intervals, finite-difference Greeks, and path simulation for path-dependent payoffs. The simulation interfaces accept user-defined payoff functions, enabling transparent construction of custom contracts while reporting numerical uncertainty.https://github.com/r-universe/aim-it4/actions/runs/36224023902Tue, 28 Jul 2026 03:19:50 GMTCustomDerivative0.2.0successhttps://aim-it4.r-universe.devhttps://github.com/aim-it4/customderivative
