Struct GammaMatrix 

pub struct GammaMatrix { /* private fields */ }

Trait Implementations

impl Clone for GammaMatrix

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GammaMatrix

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

Formats the value using the given formatter.

impl Inference for GammaMatrix

type Mat = ArrayBase<OwnedRepr<f32>, Dim<[usize; 2]>>

type Scalar = f32

fn posterior_mean(&self) -> &Self::Mat

fn posterior_sd(&self) -> &Self::Mat

fn posterior_log_mean(&self) -> &Self::Mat

fn posterior_log_sd(&self) -> &Self::Mat

fn posterior_sample(&self) -> Result<Self::Mat>

fn posterior_log_sample(&self, seed: u64) -> Result<Self::Mat>

Draw a fresh sample of log λ per element. Delta-method approximation: log λ ≈ Normal(posterior_log_mean, posterior_log_sd²). Caller must have called calibrate_with(CalibrateTarget::All) first so log_mean / log_sd are populated.

fn nrows(&self) -> usize

fn ncols(&self) -> usize

impl ParamIo for GammaMatrix

type Mat = ArrayBase<OwnedRepr<f32>, Dim<[usize; 2]>>

fn to_tsv(&self, header: &str) -> Result<()>

fn to_melted_parquet( &self, file_path: &str, row_names: (Option<&[Box<str>]>, Option<&str>), column_names: (Option<&[Box<str>]>, Option<&str>), ) -> Result<()>

fn to_parquet(&self, file_path: &str) -> Result<()>

Write to parquet with default names

impl TwoStatParam for GammaMatrix

fn new(dims: (usize, usize), a: Self::Scalar, b: Self::Scalar) -> Self

New Poisson-Gamma parameter matrix

x[i,j] ~ Poisson(lambda[i,j])
lambda[i,j] ~ Gamma(a0, b0)

#Arguments

• dims - dimensions of the matrix (num of rows, num of columns)
• a - hyper parameter a0
• b - hyper parameter b0

type Mat = ArrayBase<OwnedRepr<f32>, Dim<[usize; 2]>>

type Scalar = f32

fn add_stat(&mut self, add_a: &Self::Mat, add_b: &Self::Mat)

fn update_stat(&mut self, add_a: &Self::Mat, add_b: &Self::Mat)

fn update_stat_col(&mut self, add_a: &Self::Mat, add_b: &Self::Mat, k: usize)

fn reset_stat(&mut self)

fn map_calibrate_mean(&mut self)

fn map_calibrate_sd(&mut self)

fn map_calibrate_log_mean(&mut self)

fn map_calibrate_log_sd(&mut self)

fn calibrate(&mut self)

Calibrate all posterior quantities (mean, sd, log_mean, log_sd)

fn calibrate_with(&mut self, target: CalibrateTarget)

Calibrate only the posterior quantities specified by target.
