How to use this tool

  1. Enter observed correlation, reliability of x, reliability of y.
  2. Use the displayed units and confirm the model assumptions.
  3. Calculate and compare the outputs against your input scenario.

Try this example

{
  "r": 0.5,
  "relx": 0.8,
  "rely": 0.9
}

Accuracy and scope

Values outside [-1,1] indicate incompatible estimates or assumptions and are not silently clipped. Requires uncorrelated classical errors.
