Apache Commons Math and Groovy -- Argument Type?
Got this 2.4.5 Groovy error trying to perform a covariance calc:
groovy.lang.MissingMethodException: No signature of method:
org.apache.commons.math3.stat.correlation.Covariance.covariance() is
applicable for argument types: ([Ljava.lang.Double;, [Ljava.lang.Double;)
covariance() requires two double arrays, and that's what I provided, so
what gives?
Do I need to cast the Groovy/Java array into another type?
Any advice is much appreciated!

That did it, thanks! Thought I tried primitives earlier, but apparently
not...

Change to double[] instead of Double[].

Sorry, code sample:
import org.apache.commons.math3.stat.correlation.Covariance
import org.apache.commons.math3.stat.descriptive.DescriptiveStatistics
import org.apache.commons.math3.util.*
Double[] dblArray1 =
[0.00995630918100443,0.00425329233495364,-0.01227651365617033,0.015574186166315451]
as Double[]
Double[] dblArray2 =
[0.004630842339633734,0.003451971610807014,-0.008004809261582091,0.04068026756946197]
as Double[]
def cov = new Covariance().covariance(dblArray1, dblArray2)
println "cov: $cov"
Result:
Exception in thread "main" groovy.lang.MissingMethodException: No signature
of method:
org.apache.commons.math3.stat.correlation.Covariance.covariance() is
applicable for argument types: ([Ljava.lang.Double;, [Ljava.lang.Double;)
values: [[0.00995630918100443, 0.00425329233495364,...
Possible solutions: covariance([D, [D), covariance([D, [D, boolean)
So, how would I create the proper array argument: [D,[D ? Some Apache
Commons Math type I need to cast my java.lang.Double to?
Any suggestions much appreciated!

Could you give a code sample?
