Description Usage Arguments Value

Calculate and cache in a list various sufficient statistics of the data used by the VAMF algorithm.

1 |

`Y` |
a data matrix, typically non-negative values such as counts or TPM |

`L` |
desired latent dimension (upper bound) |

`log2trans` |
should nonzero values of Y be converted to log-scale? |

`pseudocount` |
small offset for log transformation. Transformation is g(y)=log2(pseudocount+y) for all nonzero y values |

`b1_range` |
rough guess of typical slopes for the dropout mechanism |

a list of sufficient statistics used by other vamf functions
