Function compute_statistics_for_sample 

pub fn compute_statistics_for_sample(
    lf: &LazyFrame,
    sample: &Sample,
    known_total: Option<usize>,
    options: ComputeOptions,
) -> Result<AnalysisResults>

Statistics for a LazyFrame, over the rows a crate::analysis::sampling::Sample picks from lf, which is already cut to the sample’s scope. Describe for every column; numeric percentiles, skewness, kurtosis, distribution fits and the correlation matrix as options asks.
