Ustin.Finance.Sales.Analytics

Default market-basket / affinity analytics for Ustin.Finance.Sales.Common. Targets net10.0.

  • Frequent-itemset mining — FpGrowthMiner (primary) and AprioriMiner (reference).
  • Association rules with a full interestingness-measure library: support, confidence, lift, leverage, conviction, jaccard, cosine, kulczynski, Zhang, PMI, NPMI, chi-squared.
  • Non-obvious co-occurrence detection — chi-squared significance with Benjamini-Hochberg FDR, obviousness filters (same-category / popularity-explained / known-complement) and composable novelty scorers.
  • Basket KPIs — ATV, lines & units per basket, size histogram.

Usage

using Ustin.Finance.Sales.Analytics.Features.MarketBasket;
using Ustin.Finance.Sales.Analytics.Features.UnexpectedAffinity;

// (A) What is bought together — ranked by lift
var correlations = await MarketBasket.Analyze(source)
    .MinSupport(0.005)
    .MinConfidence(0.20)
    .MaxItemsetSize(3)
    .OrderByDescending(Measures.Lift)
    .Top(50)
    .RunAsync();

// (B) Which non-obvious products show up together
var surprises = await UnexpectedAffinity.Analyze(source)
    .MinLift(1.5)
    .Significance(0.01)
    .Exclude(Obvious.SameCategory(categoryBySku))
    .Exclude(Obvious.ExplainedByPopularity(countBySku, transactionCount))
    .Top(25)
    .RunAsync();

See the project repository for the design notes, the theory behind each measure, and the roadmap (cross-sell, bundling, RFM, and — deferred — ABC analysis and unit economics).
