Sampling & Estimation

Insight Statistical Consulting has been providing expert sampling services to a range of organisations since its inception in 1989.
Sometimes these provide solutions to ad hoc questions such as:

  • How many bank accounts should be sampled to obtain a reasonable estimate of statement error? If no errors are found within the sample, what does this mean
  • What is the best estimate of bad debt provision from a large population of mobile phone accounts with a range of different credit histories?
  • Review the research methodology used to estimate fraud and error rates in large populations and how may the efficiency be improved?
