--print_csv

Switch

--print_csv FILENAME

Description

Prints the group-normalized feature/outcome values used for correlation to a csv file.

Argument and Default Value

A file path. Default: None.

Details

Known issue — MySQL-only, crashes under SQLite. oa.printGroupsAndOutcomesToCSV() checks the feature table exists via mm.tableExists(...) — a call straight into mysqlmethods, bypassing the DataEngine/QueryBuilder abstraction used everywhere else for SQLite support. Verified: under a SQLite corpus this fails immediately with sqlite3.OperationalError: near "show": syntax error (the generated SHOW TABLES-style query is MySQL syntax).

Other Switches

Required Switches:

• -d, -t, -g

• -f

• --outcome_table, --outcomes
