I tried turning on the extended debug info. The Scala output is a little
opaque (lots of - field (class $iwC$$iwC$$iwC$$iwC$$iwC$$iwC, name:
$iw, type: class $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC), but it seems
like, as expected, somehow the full array of OLSMultipleLinearRegression
objects is
Hey Sandy,
Try using the -Dsun.io.serialization.extendedDebugInfo=true flag on the JVM to
print the contents of the objects. In addition, something else that helps is to
do the following:
{
val _arr = arr
models.map(... _arr ...)
}
Basically, copy the global variable into a local one.
