coxph() command design and data setup
...hat I have chamber %in% treatment right in representing my data, but how do I account for room as a block? Additionally, I have a frequency column in data.table that indicates how many of a particular observation occurred in each row. Is it appropriate to assign this column as a weigh argument in cosph? If so, how is that done? I can send sample data if necessary. Thanks for any help! Justin Montemarano [[alternative HTML version deleted]]
