Method: GECS.quickMeans

Defined in:
lib/GECS.rb

.quickMeans(bagOfHolding, id) ⇒ Object

Add the following parameter to the data and effects of a specified experiment: mean, original method, 95% confidence. This is a quick way to summarize results when more complicated options are not needed. All values are computed as Floats with no respect for the original data type or its precision.

bagOfHolding

A BagOfHolding.

id

Experiment id.
