How can I change hyperparameters as in ranger?

[NamLQ]

Hi!

In ranger, I can tweak these arguments: num.trees, mtry, min.node.size, splitrule, and num.random.splits. How can I do so in missRanger?

Thank you very much!

Hello,
At the moment, they are set to a fixed default (usually they work in an okay way). But I will have a look at it. It should not be tricky to implement.

Check now via "install_github" to use missRanger with ranger defaults. Use the ellipsis "..." to change the defaults.

Now you can e.g. use

irisWithNA <- generateNA(iris)
missRanger(irisWithNA, pmm.k = 3, num.trees = 200, splitrule = "extratrees")
