To Test for Randomization When $X _ { \mathrm { i } }$

question 32

Multiple Choice

To test for randomization when $X _ { \mathrm { i } }$ is binary,

• A) you regress \(X _ { \mathrm { i } }\) 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.
