Save it into your B510 folder, and be sure to submit a correct libname statement, so you can use it in SAS properly.510data.xlsThe SAS Excel file you will need for homework 2. Save it into your B510 folder, and import it using the SAS Import Wizard. Be sure to save your commands for importing this dataset, as instructed in the homework.Homework 3Due Thursday, February 4th.homework3_2010.docThis homework assignment asks you to use three permanent SAS datasets from the Tecumseh Community Health Study. These datasets are from a longitudinal community study and represent data for adults collected in Round 1, Round 2, and Round 3 of data collection. The same participants were included in all these datasets, however, there was some dropout due to attrition over time.You are asked to stack the datasets, and then to match-merge the datasets by ID. You will also create some new variables using recodes and transformations.

This homework assignment uses the afifi.dat raw data, which you will read into SAS and create a permanent SAS dataset. You will carry out several simple linear regressions, and some multiple regressions. You will check the multiple regression for collinearity.homework5_2010_key.docAFIFI.DATThe raw data to use with homework 5.Revised Homework 6Due Thursday, February 25th.revised_homework6_2010.docREVISED VERSION. This homework assignment uses the afifi.sas7bdat permanent SAS dataset, which you created in homework 5. You will fit a linear regression model with dummy variables as predictors, fit an ANOVA model, and an ANCOVA model with interactions, and fit separate linear regression models.homework6_2010_key.docafifi.sas7bdatThe permanent SAS dataset to use with homework 6.Homework 7REVISED DUE DATE Tuesday, March 23rd.new_revised_homework7_2010.docThis homework assignment uses the permanent SAS dataset, afifi2.sas7bdat, that was created in the last homework problem set. In this problem set, you will create some new categorical variables and formats to display the variables. You will use Proc Freq in SAS to create frequency tabultations and cross-tabs, and fit some logistic regression models. (Note: the due date is now Tuesday, March 23rd.
