  "Description": "Estimation methods for zero-inflated Poisson factor\nanalysis (ZIPFA) on sparse data. It provides estimates of\ncoefficients in a new type of zero-inflated regression. It\nprovides a cross-validation method to determine the potential\nrank of the data in the ZIPFA and conducts zero-inflated\nPoisson factor analysis based on the determined rank.",
