Struct AdditiveWiggleBlockLayout 

pub struct AdditiveWiggleBlockLayout<'a> {
    pub family: &'a str,
    pub n_outputs: usize,
    pub additive_blocks: &'a [usize],
    pub wiggle_block: Option<usize>,
}

Static description of an additive-plus-wiggle family’s block layout, used to build the per-block BlockEffectiveJacobian in one place.

additive_blocks lists the block ids that contribute a linear additive term to a single family output; each such block drives output block_idx (i.e. own_output == block_idx). wiggle_block is the optional nonlinear link-modulation block whose effective linear Jacobian is all zeros; its row count is taken from the first additive block’s design.

Fields

family: &'a str

Family name used as the message prefix and effective_design context, e.g. "SurvivalLocationScaleFamily".

n_outputs: usize

Total number of stacked family outputs (e.g. 3 for survival location-scale, 2 for Binomial location-scale).

additive_blocks: &'a [usize]

Block ids that contribute a linear additive term to their own output.

wiggle_block: Option<usize>

Optional nonlinear link-modulation block id (all-zero linear Jacobian).

Implementations

impl AdditiveWiggleBlockLayout<'_>

pub fn block_effective_jacobian( &self, specs: &[ParameterBlockSpec], block_idx: usize, ) -> Result<Box<dyn BlockEffectiveJacobian>, String>

Build the BlockEffectiveJacobian for block_idx under this layout.

• An additive block returns an AdditiveBlockJacobian over its effective design with own_output = block_idx and n_family_outputs = n_outputs.
• The wiggle block returns an AdditiveBlockJacobian over an (n × p_wiggle) zero design anchored at own_output = 0, with n read from the first additive block’s design.
