Struct PmlData 

pub struct PmlData<'a> {
    pub design: &'a [f64],
    pub offset: &'a [f64],
    pub counts: &'a [f64],
    pub cell_index: &'a [usize],
    pub subject_start: &'a [usize],
    pub subject_total: &'a [f64],
}

One gene’s data, in the layout NEBULA’s C++ expects.

Cells must already be grouped by subject, which is what makes subject_start a valid block partition. Only the positive counts are stored: counts[i] is the count in cell cell_index[i].

Fields

design: &'a [f64]

Design matrix, row-major n_cells * n_beta.

offset: &'a [f64]

Log offset per cell, length n_cells.

counts: &'a [f64]

The positive counts, in increasing cell order.

cell_index: &'a [usize]

Cell index of each entry of counts, zero-based and increasing.

subject_start: &'a [usize]

Start of each subject’s block plus a trailing n_cells, length k + 1.

subject_total: &'a [f64]

Total count per subject, length k. nebula’s cumsumy.

Implementations

impl PmlData<'_>

pub fn n_cells(&self) -> usize

Number of cells.

Returns

The length of offset, which defines the cell axis.

pub fn n_subjects(&self) -> usize

Number of subjects.

Returns

One fewer than the length of subject_start, or zero if that is empty.

pub fn n_beta(&self) -> usize

Number of fixed effects.

Returns

The design width implied by design.len() and n_cells, or zero when there are no cells.

Trait Implementations

impl<'a> Clone for PmlData<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for PmlData<'a>

impl<'a> Debug for PmlData<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
