  • Example
Perform the analysis
  • Enter your data
  • Specify information about the elements
  • Specify the gap sensitivity in the Pareto chart
  • Specify options for the variance pool
  • Estimating missing standard deviations

Methods and formulas
  • Calculations for the design statistics
  • Calculations for the specification limits
  • Calculations for the gap distribution (long-term statistics)
  • Calculations for the gap distribution (short-term statistics)
  • Calculations for the mean pool and the variance pool
