Decision Tree - Minbucket

decisiontree

#1

Hi, I ran a decision tree in R using min bucket 2 and i obtained a tree with about six layers (depth). First split divided the dataset into 69% and 31% data respectively and so on. I had about 800K rows of data. Later I changed min bucket to 8000 (1%) and I ran it again. However, I got an error saying “it’s just a root not a tree”. Pls help…
