Three-interval simulation RMSE calculator

For the specified three-interval calibrated-simulation convention, divide squared simulation-minus-meter residuals by the number of intervals; this does not establish a universal acceptance threshold.

RMSE=d12+d22+d323\mathrm{RMSE} = \sqrt{\frac{d_{1}^{2} + d_{2}^{2} + d_{3}^{2}}{3}}

Worked example

Given

  • d1d_{1} = -500 kWh
  • d2d_{2} = 800 kWh
  • d3d_{3} = -200 kWh
RMSE=(−500)2+8002+(−200)23≈556.8\mathrm{RMSE} = \sqrt{\frac{{\left(-500\right)}^{2} + {800}^{2} + {\left(-200\right)}^{2}}{3}} \approx 556.8
