Ross Laidlaw commented on CLIMATE-541:
--------------------------------------
I've spoken with [~ploikith] and [~kwhitehall] for advice, and the desired
method to be ported over is
'calcRootMeanSquaredDifferenceAveragedOverTimeAndDomain':
{code}
def calcRootMeanSquaredDifferenceAveragedOverTimeAndDomain(evaluationData,
referenceData):
sqdiff = (evaluationData - referenceData)** 2
rms = np.sqrt(sqdiff.mean())
return rms
{code}
Both Paul L and Kim said that they didn't view the similar method
'calcRootMeanSquareDifferenceAveragedOverTime' as being particularly useful as
a metric. I'll therefore port over the '...AveragedOverTimeAndDomain' method
as the following class in ocw/metrics.py:
{code}
class RMSError(BinaryMetric):
def run(self, eval_dataset, ref_dataset):
sqdiff = (eval_dataset.values - ref_dataset.values) ** 2
return numpy.sqrt(sqdiff.mean())
{code}
> Port 'calcRootMeanSquareDifferenceAveragedOverTimeAndDomain' method over to
> ocw/metrics.py module

> Port the method from rcmet/src/main/python/rcmes/toolkit/metrics_kyo.py over
> to the ocw/metrics.py module. There's also a suggestion to shorten the name
> of this method to 'RMSDifference' (or similar).
