PHMY 880 SURV. ANALYSIS (10/2, LAST FOR
MIDTERM) correctly answered to pass
1. with cox survival regression
time to event
model, what is Y

2. what is question of interest
how long something will last
with cox survival regression

3. this is incomplete information
censoring
about the time to event for
some individuals in the study

4. when does censoring occur when the event of interest (e.g., death,
relapse, or
failure) has not been observed for all
subjects by the end of the study period or
when subjects are lost to follow-up

5. T/F: cox survival regression 9. why might censoring occur
accounts for censoring concerns

6. T/F: event with time to event
could be good or bad and time
could be any units such as years,
months, weeks, or days

7. what model is preferred
method to handle time to
event outcome and censoring
observations

8. even though linear regression
deals with continuous variables
and time to event is continuous,
why is it not pre- ferred method
