# copulaSFM 0.2.0

## Major Improvements

- Added support for two-parameter copula families (Student-t, BB families).
- Extended `copSFM()` to accept `RHO2`, `LB2`, and `UB2`.
- Updated `TE()` to handle two-parameter copulas.
- Added `nSim` and `seed` arguments for reproducible Monte Carlo simulation.
- Improved numerical stability of likelihood and technical efficiency estimation.
- Expanded documentation to clearly describe supported copula families and parameter bounds.

## Minor Changes

- Code refactoring for improved stability.
- Documentation improvements and formatting updates.
