Report from self-normalized inverse propensity scoring.

Fields

policy_name: String

policy_version: Option<String>

num_observations: usize

supported_observations: usize

overlap_failure_count: usize

support_fraction: f64

Supported rows divided by all valid rows. This is not a causal guarantee; it is an explicit overlap diagnostic.

ips: Option<f64>

Ordinary IPS: sum(importance_weight * reward) / N.

self_normalized_ips: Option<f64>

Self-normalized IPS: sum(weight * reward) / sum(weight).

effective_sample_size: Option<f64>

Kish effective sample size over supported importance weights.

max_observed_importance_weight: Option<f64>
