In every iteration, when the process suggests removing a categorical variable, it means removing all its dummy variables (levels) at once, not just one(e.g. Removing is_red, is_blue, is_fellow all together for color) L1 Regularization is another way to reduce the number of features Use ...
In doing a data step operation, RevoScaleR reads in a chunk of data read from the original data set, including only the variables indicated invarsToKeep, or omitting variables specified invarsToDrop. It then passes the variables needed for data transformations back to R for manipulation: ...
There is growing support and interest in postsecondary interdisciplinary environmental education, which integrates concepts and disciplines in addition to providing varied perspectives. There is a need to assess student learning in these programs as well
I am using this select(dat, -SEQN) %>% names() to get the names for all variables except the id (SEQN). If you want to exclude other variables from the table one, use the sign -. However, in table one for publication, I need to show the labels. For this, I will use...
