vivid include all variables in the data, even thought I did not list them in the model

[jielab]

Hi, there:

Please see the screenshot below. Although I only listed 6 covariates in my randomForest() model, vivi() output all variables. Those unlisted variables show up as 0.00. I hope that vivid did not actually do anything with those variables.

Best regards, Jie

Hi,

Since all the variables are included in the data argument that is passed to vivid (despite only a selection of them being used in the model), vivid deals with these variables by just ignoring them and setting the values to zero. I suggest that you read either the vignette found at: https://alaninglis.github.io/vivid/articles/vividVignette.html

Or either paper related to the package, found at:

1) https://www.tandfonline.com/doi/pdf/10.1080/10618600.2021.2007935 2) https://journal.r-project.org/articles/RJ-2023-054/RJ-2023-054.pdf
