Struct SmoothMonotoneResult 

#[non_exhaustive]
pub struct SmoothMonotoneResult {
    pub fitted: Vec<f64>,
    pub beta0: f64,
    pub beta1: f64,
    pub w_coefficients: Vec<f64>,
    pub iterations: usize,
    pub converged: bool,
}

Result of Ramsay monotone smoothing via integral-of-exponential representation.

The fitted values are structurally monotone: since f'(t) = β₁·exp(w(t)) and exp(w(t)) > 0 always, the sign of β₁ determines direction. This guarantee holds even if the Gauss-Newton iteration did not fully converge.

R baseline

Analogous to fda::smooth.monotone (R fda package).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fitted: Vec<f64>

Fitted values at the input argvals (length m). Structurally monotone.

beta0: f64

Intercept β₀ (value of the fitted function at argvals[0]).

beta1: f64

Scale β₁. Positive → nondecreasing fit; negative → nonincreasing fit.

w_coefficients: Vec<f64>

B-spline coefficients for the log-rate function w(u) (length = actual nbasis).

iterations: usize

Number of Gauss-Newton iterations executed.

converged: bool

Whether the Gauss-Newton update norm fell below 1e-8 before max_iter.
