Description

Most Python models under the pipeline API are implemented as JavaModel wrappers. However, we didn't provide methods to extract information from model. In SPARK-7647, we added weights and intercept to linear models. This JIRA is to list all missing model methods, create JIRAs for each, and link them here.
