dataset = ICU begin description This data set comes from STATLIB DASL. Available from (http://lib.stat.cmu.edu/DASL/Datafiles/ICU.html). Also see Hosmer and Lemeshow (2000, pp. 23-25). Description: The data consist of 200 subjects from a larger study on the survival of patients following admission to an adult intensive care unit (ICU). The study used logistic regression to predict the probability of survival for these patients until their discharge from the hospital. The dependent variable is the binary variable Vital Status (STA). Nineteen possible predictor variables, both discrete and continuous, were also observed. ID= ID number of the patient STA= Vital status (0 = Lived, 1 = Died) AGE= Patient's age in years SEX= Patient's sex (0 = Male, 1 = Female) RACE= Patient's race (1 = White, 2 = Black, 3 = Other) SER= Service at ICU admission (0 = Medical, 1 = Surgical) CAN= Is cancer part of the present problem? (0 = No, 1 = Yes) CRN= History of chronic renal failure (0 = No, 1 = Yes) INF= Infection probable at ICU admission (0 = No, 1 = Yes) CPR= CPR prior to ICU admission (0 = No, 1 = Yes) SYS= Systolic blood pressure at ICU admission (in mm Hg) HRA= Heart rate at ICU admission (beats/min) PRE= Previous admission to an ICU within 6 months (0 = No, 1 = Yes) TYP= Type of admission (0 = Elective, 1 = Emergency) FRA= Long bone, multiple, neck, single area, or hip fracture (0 = No, 1 = Yes) PO2= PO2 from initial blood gases (0 = >60, 1 = ²60) PH= PH from initial blood gases (0 = ³7.25, 1 <7.25) PCO= PCO2 from initial blood gases (0 = ²45, 1 = >45) Bic= Bicarbonate from initial blood gases (0 = ³18, 1 = <18) CRE= Creatinine from initial blood gases (0 = ²2.0, 1 = >2.0) LOC= Level of consciousness at admission (0 = no coma or stupor, 1= deep stupor, 2 = coma) end description begin variables Co1 0 = ID Co1 1 = STA Col 2 = AGE Co1 3 = SEX Co1 4 = RACE Co1 5 = SER Co1 6 = CAN Co1 7 = CRN Co1 8 =
