4 Interpret regression results in the literature (10pct) The final task involves just interpretation, no separate analysis is needed. Table 1 displays linear regression results from Dawel et al. (2020). You do not have to read the paper in order to answer these questions, but it is uploaded on canvas (files/readings/dawel+2020FiP.pdf) in case you want understand more. The authors estimate a model PHQ9; Bo + B Age Age₁ + B Gender Genderi+ + B Education Education + + €i. Variable explanations: PHQ-9 Patient Health Questionnaire, used to detect depression. Larger number mean worse mental health. WSAS Work and Social Adjustment Scale, measures COVID caused dis- ruptions in life. Age in years Education in years Other variables should be easy to understand, except I cannot find what exactly does "gender" mean. Answer the following questions: 1. Do those who have a partner have better mental health (as measured by PHQ-9)? Is the effect statistically significant? 2. What is the effect of COVID exposure? Is it improving or worsening mental health? Is the effect statistically significant? 3. How is Financial distress related to mental health? Is the effect sta- tistically significant?
