Universal Service Administrative Company USAC : Econometrica provides USAC with audit support consisting of stratified random sampling, statistical modeling, and analysis services for its Payment Quality Assurance PQA Internal Audit Division which includes the Schools and Libraries, Lifeline, High Cost, and Rural Health Care programs , the Billed Entity Application Reimbursements program, and the High Cost Mobility Fund.

For the High Cost Mobility Fund, Econometrica prepares sampling plans for audits of the following eight High Cost programs to ensure compliance with FCC rules and regulations: Connect America Fund Phase I, Connect America Fund Phase II, Connect America Fund Phase II Auctions, Alternative Cost America Model, Mobility Fund, Rural Broadband Experiments, Connect America Fund Broadband Loop Support, and Alaska Plan.

Because these audits address discrete cases of broadband deployment, rather than continuous funding disbursements, binomial and hypergeometric distributions are used to compute key parameters in the sampling plans.

By analyzing past data on improper payments, Econometrica has been able to substantially reduce the minimum sufficient sample sizes necessary to meet the required precision criteria of a percent confidence level and a 3-percent margin of error. Work included developing a sampling plan and creating a sample of RAC-reviewed claims for use in the ongoing RAC validation.

Consistent soil sampling is the key to getting accurate soil test results. Crop Quest takes soil samples for clients under contract and provides custom soil sampling services for non-contract clients. Our agronomists sell no products and make unbiased fertilizer recommendations, based on certified laboratory analysis of each sample.

Recommendations take into consideration yield goal, carryover fertilizer levels, and other variables. Much more than just a scout.

In a material stockpile, its composition and quality can greatly vary throughout due to production cycles, shape segregation and particle size. If the sample is biased, it will affect the test results. Therefore, getting an unbiased sample — one that wholly represents the material — is crucial, and it is obtained through a systematic collection.

Our collection process follows industry-accepted methods and uses the appropriate equipment. Our care for the details ensures the representative sample will be unbiased at every step of the process. To start gathering the sample, our field engineers take small amounts of material throughout the entire pile.

We have dedicated sampling arms for this purpose that meet ISO and ASTM standards and are operated by experienced professionals.

These many small samples will capture any potential differences that exist in the many sections of the stockpile. We will then combine these smaller samples at the site to create a homogeneous representative sample of the material, maintain sample moisture, reduce preparation time at the laboratory and return excess material to the sampling site.

These efforts reduce disposal costs and prevent excess material loss for the client. This final sample will allow us to get the most accurate analysis of the stockpile. Our team is proficient with ASTM and ISO methods for sampling in mineral processing. These practices are accepted and standard in the industry, so you can trust in the procedure and accuracy of your results.
