Detailed Description

Bundled dataset: features, responses, and group labels.

Convenience struct that groups a feature matrix, a response vector, and the set of unique group labels. Used primarily for passing data through the training pipeline.

Member Data Documentation

feature_names

std::vector<std::string> const ppforest2::stats::DataPacket::feature_names

Original feature column names from the CSV header.

When populated, feature_names[j] is the header label for column j of x. Empty when data is simulated.

group_names

std::vector<std::string> const ppforest2::stats::DataPacket::group_names

Original group label names, indexed by integer code.

When populated, group_names[i] is the original string label that maps to integer code i. Empty when data is not read from CSV (e.g., simulated data).

groups

std::set<types::Response> const ppforest2::stats::DataPacket::groups

Set of distinct group labels.

x

types::FeatureMatrix const ppforest2::stats::DataPacket::x

Feature matrix (n × p).

y

types::Vector<types::Response> const ppforest2::stats::DataPacket::y

Response vector (n).
