1The mean score difference measures the difference in the estimated mean psychological distress score between ‘constant and long dry’ and each other drought category.
2The ‘very dry’ drought category is dropped in the regression of missing meals because this variable perfectly predict the failure (missing meals =0), causing this variable’s coefficient to be unidentified.
