Dear R users,
I need to analyze data generated from a partial two-by-two factorial design:
two levels for drug A (yes, no), two levels for drug B (yes, no); however,
data points are available only for three groups, no drugA/no drugB, yes
drugA/no drugB, yes drugA/yes drug B, omitting the fourth group of no drugA/yes
drugB. I think we can not investigate interaction between drug A and drug B,
can I still run model using R as usual: response variable = drug A + drug B?
any suggestion is appreciated.
Thank you very much!
Yuan Chun Ding
