## Summary Implement a Negative Binomial (NB) error model to capture overdispersion in single-cell CNV data. ## **Key Changes** ### **phylonco-beast** **Updated:** 1. **NestedBD.v1.9.6.jar** 2. **NestedBD.v1.9.6.src.jar** 3. **NestedBD.version.xml** 4. **version.xml** ### **phylonco-lphy** 1. **NegativeBinomialErrorModel.java** Implements NB likelihood with dispersion parameter k. Generates observed alignment C from true alignment A. 2. **PhyloncoImpl.java** Registers the new error model with the LPhy SPI. ### **phylonco-lphybeast** 1. **NegativeBinomialErrorModelToBEAST.java** Converts the LPhy NB error model into BEAST2 XML. Maps to the NestedBD package implementation. 2. **LBPhylonco.java** Registers the new BEAST converter.
