multi-cell test
ex. # of frequency exposure
ex. creatives
A/B test
no control group
cannot monitor lift
test different versions of ads
split testing
which ad has lowest cost per result
multi-cell lift test
limitations
not enough statistical power
Reasons
limited frequency/duration
other overlapping campaigns running
too small control group vs test
how to resolve
keep testing
use results
collect more data
hard to isolate variables
person can be in both test & control group
ex. people located in same household
you can't track all data/unknowns
ex. cash transactions
ex. device switching
test/control groups may have outliers
windsorization - upper/lower bound setting for outliers
Observational method
