Struct SurvivalMarginalSlopeFrozenOffsetChart 

pub struct SurvivalMarginalSlopeFrozenOffsetChart { /* private fields */ }

A nonlinear baseline chart over already-prepared marginal-slope offsets.

Construction subtracts the initial parametric baseline from the prepared offset channels exactly once. Candidate evaluations add a new baseline to that same frozen residual. Consequently candidate theta values cannot move any prepared time design, wiggle knot, penalty, or feasibility cone; only the three row-offset value channels move, with analytic first and second derivatives supplied by the same evaluation.

Implementations

impl SurvivalMarginalSlopeFrozenOffsetChart

pub fn new( age_entry: &Array1<f64>, age_exit: &Array1<f64>, initial_config: &SurvivalBaselineConfig, prepared_offset_entry: &Array1<f64>, prepared_offset_exit: &Array1<f64>, prepared_derivative_offset_exit: &Array1<f64>, ) -> Result<Self, String>

pub fn target(&self) -> SurvivalBaselineTarget

pub fn initial_theta(&self) -> &Array1<f64>

pub fn theta_bounds(&self) -> (&Array1<f64>, &Array1<f64>)

Declared finite domain of this frozen nonlinear chart. These are the same coordinate bounds used by the legacy standalone baseline solver, now owned by the chart so a joint solver and its terminal certificate cannot silently choose a different domain.

pub fn fixed_offsets(&self) -> (&Array1<f64>, &Array1<f64>, &Array1<f64>)

pub fn evaluate_initial( &self, ) -> Result<SurvivalMarginalSlopeOffsetGeometry, String>

pub fn evaluate( &self, theta: &Array1<f64>, ) -> Result<SurvivalMarginalSlopeOffsetGeometry, String>
