Multiple Choice
To test for randomization when Xi is binary,
A) you regress Xi,on all W's and compute the F-statistic for testing that all the coefficients on the W's are zero.(The W's measure characteristics of individuals,and these are not affected by the treatment. )
B) is not possible,since binary variables can only be regressors.
C) requires reordering the observations randomly and re-estimating the model.If the coefficients remain the same,then this is evidence of randomization.
D) requires seeking external validity for your study.
