Expand description

Result of statistical analysis on binary data.

Fields§

§entropy: f64

§compression_percent: f64

Ideal compression percentage based on entropy.

§chisquare: f64

Chi-square test value.

§p_value: f64

p-value of chi-square test.

§mean: f64

Arithmetic mean of all data bytes.

§pi_estimate: f64

§byte_frequencies: Option<Vec<(u8, usize, f64)>>

Byte frequency table: (value, count, fraction).

§bit_frequencies: Option<[(usize, f64); 2]>

Bit frequency table: [(count, fraction) for 0, 1].
