Please identify and explain 2 regression/correlation constructs in the case scenario below:Cancer, Endocrinology:Obesity is very common in American society and is a risk factor for breast cancer in postmenopausal women. One mechanism explaining why obesity is a risk factor is that it may raise estrogen level in women. In particular, one type of estrogen, serum estradiol, is a strong risk factor for breast cancer. To better assess thes relationships, reaearchers studied a group of 151 African American and 60 Caucasian prememopausal women. Adiposity was measured in two different ways: BMI=weight (kg)/height(m2) and waist-hip ratio (WHR)=waist circumference/hip circumference. BMI is a measure of overall adiposity, whereas WHR is a measure of abdominal adiposity. In addition, a complete hormonal profile was obtained, including serum estradiol (ES_1). Finally, other breast-cancer risk factors were also assessed among these women, including (1) ethnicity (ETHINC=1 in African American, = 0 if Caucasian), (2) age (ENTAGE), (3) parity (NUMCHILD= number of children)(4) age at first birth (AGEFBO), (5) any children (ANYKIDS = 1 if yes, = 0 if no), (6) age at menarche (AGEMNRCH = age when menstrual periods began) The data are provided in Data Set ESTRADL.DAT.
