In the following i am studying life expectancy as an example: where I have dummies for a person being male, female, smart, wealthy. The base reference is a child who is not smart or wealthy.
Life expectancy=β_1 Male+β_2 Female+β_3 Wealthy+β_4 Smart+β_5 (MALE Wealthy)+β_6 (FEMALE Wealthy)+β_7 (SMART Wealthy)+β_8 (MALE Wealthy)+β_9 (FEMALE Wealthy)+β_10 (MALE SMART Wealthy)+β_11 (FEMALE SMART Wealthy)
How should β_10 and β_11 be interpreted?
