To do this, we convert the listing in data sets by using PROC REPORT and then after that we can compare it by using PROC COMPARE.Ĥ. How would you perform the validation for the listing, which has 400 pages?Īns:- It is not possible to perform the validation for the listing having 400 pages manually. We can perform this validation for TLG by checking the output manually and for analysis data set it can be done using PROC COMPARE.ģ. If this output is same as the output generated by the SAS programmer’s output then the program is considered to be valid. In this process validator write the program and generate the output. Describe the validation procedure? How would you perform the validation for TLG as well as analysis data set?Īns:- Validation procedure is used to check the output of the SAS program generated by the source programmer. Phase 4: The 4 phase study includes the post marketing studies including the drug’s risk, benefits etc.Ģ. Phase 3: The experimental drug or treatment is given to a large group of people (1000-3000) to see its effectiveness, monitor side effects and compare it to commonly used treatments.
Phase 2: The experimental drug or treatment is given to a large group of people (100-300) to see that the drug is effective or not for that treatment.
Phase 1: Test a new drug or treatment to a small group of people (20-80) to evaluate its safety. Ans:- These are the following four phases of the clinical trials:
