Our strengths

  • Litigation Services
    • In commercial litigation, we estimate key quantities at issue, compose expert reports, review and critique opposing expert reports, and provide expert testimony in court settings. We help you to reveal both promising and problematic analyses, so you know the statistical strengths and weaknesses of your case.
  • Modeling and Data Analytics
    • Whether you have a small amount of data or several massive databases, we can make sense of your data through statistical modeling and machine learning, providing key insights, estimates, predictions, and decisions.
  • Statistical Analysis and Sampling
    • We use statistical analysis and sampling techniques to make scientifically valid inferences using a sampled portion of the data. This process leads to estimates with high accuracy and precision, often at a fraction of the cost of a complete (census) or manual review of the data.

Areas of application


  • StatAcumen has assisted law firms in matters relating to healthcare, insurance, discrimination, elections, jurisdiction, and corporation/government breach of agreements; additional areas of interest are audits, fraud and theft, labor and employment, public policy, government regulation, and education. We estimate key amounts at issue, review and critique reports, compose expert reports, and provide expert testimony in court settings. Dr. Erhardt has given depositions as an expert witness in statistics.
  • In our litigation work, we always assume you want to know the right answer, whether or not it favors your position. We will work with your data to uncover both promising analyses and potential problems because we believe that you need to have unbiased and well-supported facts to make the best decisions in litigation matters.
  • When giving testimony, the expert statistician is an educator. Expert witnesses need to be able to explain sophisticated statistical concepts in common sense terms that are accessible. If it is difficult to grasp the concepts being articulated by an expert, the accompanying analyses could be discarded during deliberations. With over two decades of teaching experience and numerous teaching awards, recognitions, and fellowships, Prof. Erhardt is able to present sophisticated concepts in common sense terms, without the use of jargon.
  • We have experience taking on much of the time-consuming preparations that expert testimony requires, which can range from reviewing briefs and other expert testimony and exhibits, data cleaning and visualization, performing preliminary and complex statistical analysis, developing concise visual summaries of evidence and results, writing reports, and ultimately providing testimony.
  • Outside of direct testimony, we also provide more targeted statistical consulting support and can author independent analyses for numerous matters intended to be resolved via mediation or arbitration or otherwise outside of the litigation arena.
  • We offer flexible pricing options for all expert testimony or consulting and price all of our engagements on a case-by-case basis. Depending on your needs and timeline, we’re able to offer our services on a per-project, hourly, or retainer basis. Our statisticians and consultants offer everything from preventive work to analysis and testimony, and can bill for these services together or separately. Our expertise and experience allows us to offer ultra-fast turnaround times on analytical work – so even if you’re working on a very short timeline, we can definitely provide you with our comprehensive assistance.
