Type Members

  1. abstract type FitState

    Permalink

    Type for the state that the test maintains between variants.

Abstract Value Members

  1. abstract def fitStatePerPhenotype: Boolean

    Permalink

    If true, the FitState uses per-phenotype information and must be refit for each phenotype.

    If true, the FitState uses per-phenotype information and must be refit for each phenotype. If false, the FitState only depends on the covariates

  2. abstract def init(phenotypes: Array[Double], covariates: DenseMatrix): FitState

    Permalink

    Initializes a FitState for a (covariate matrix, phenotype array) pair.

    Initializes a FitState for a (covariate matrix, phenotype array) pair.

    As much memory allocation as possible should be performed in this step to avoid allocations in the per-row fit.

  3. abstract def resultSchema: StructType
