Question: Table (available on the companion website) gives data on a random sample of 40 adults about their mental health, classified as well, mild symptom formation, moderate symptom formation, and impaired in relation to two factors, socio-economic status (SES) and an index of life events (a composite measure of the number and severity of important events in life, such as birth of a child, new job, divorce, or death in a family for occurred within the past three years).
(a) Quantify mental health as well = 1, mild 2, moderate = 3, and impaired = 4 and estimate an ordinal logit model based on these data.
(b) Now reverse the order of mental health as 1 for impaired, 2 for moderate, 3 for mild, and 4 for well and reestimate the OLM.
