Methods

• classmethod AddComponentClass(Sclass As %String, Desc As %String = "") as %Status

Add class to Monitor

• classmethod CalcSignif(Tval, Degrees, ByRef NullProbability As %String)

Returns NullProbability = 0: Null hypothesis < 90% probability Returns NullProbability = 1: Null hypothesis < 95% probability Returns NullProbability = 2: Null hypothesis < 99% probability Returns NullProbability = 3: Null hypothesis < 99.9% probability Returns NullProbability = 4: Null hypothesis > 99.9% probability
