Configuration for zero-inflated distribution.

Fields

zero_probability: f64

Probability of a structural zero (0.0-1.0). Higher values = more zeros.

base_distribution: ZeroInflatedBaseDistribution

Type of base distribution for non-zero values.

lognormal_mu: f64

Mu parameter for log-normal base distribution.

lognormal_sigma: f64

Sigma parameter for log-normal base distribution.

exponential_lambda: f64

Lambda parameter for exponential base distribution.

poisson_lambda: f64

Lambda parameter for Poisson base distribution.

min_value: f64

Minimum non-zero value.

max_value: Option<f64>

Maximum value (clamps output).

decimal_places: u8

Number of decimal places for rounding.
