vizrank: number of instances require a minimum setting
|Reported by:||lareooreal||Owned by:|
|Severity:||major||Keywords:||vizrank number of instances|
I frequently use visrank to assemble marker combinations. However the algorithm has its trouble with data with lots of NA (non availables). The problem is that in a combination of variables the number of #instances gets lower and lower, while the classification accuracy seems to be good (no wonder with few instances !!)
Is ist possble to implement under "settings" a field that the number of instances shall be larger then a value to be selected?
#instances > 10 for example
This would even save time in the vizrank evaulation loop rejecting non relevant marker combinations because they have insufficient instances.
