fit Group
open override fun fitGroup(sortedData: DoubleArray, startIndex: Int, endIndex: Int): GroupFitResult(source)
Fits every candidate family to the observations in the index range from startIndex until endIndex, returning those that succeeded and those that did not.
Implementations must not throw when an individual family fails to fit; a failure is an expected outcome to be reported, not an exceptional one.
Parameters
sorted Data
the observations in non-decreasing order
start Index
the inclusive start index of the group
end Index
the exclusive end index of the group
