Hi,
I am a biostatistician/sas consultant.
USFDA have permitted and encouraged Adaptive Designs in clinical trials.
I wish to apply these designs in clinical research.
I request all to infprm me the sites where can I get SAS programs free or at
minimum cost.
Thanks

HI
1) Request to experts to elaborate advantages of learning SAS to new Biostatisticians (students).
2)Which are the minimum modules new Biostatisticians should learn before entering clinical trials?
3)Whether biostatisticians should learn SAS 8.2 or SAS 9.1?
4) SAS training is very expensive for students so how to learn SAS with the minimum expenditure?
Thanks,
Anil

Thanks a lot for your references.
This is a problem which is given to new sas learners to understand ' concept algorithm'.
Even though most of the students have understood algorithm,not a single
experienced SAS programmer could write a SAS program.
This is the reason to post this problem.
Experienced SAS programmers are requested to help.
Thanks in anticipation.

Thanks for the solution.
The use of expoenetial is not allowed.
The SAS program should have only addition,subtraction,multiplication and division mathematical operators.

Find square root of any positive real number without using any function (like sqrt).
Basic arithmetic operators (addition,subtraction,multiplication & division) are allowed. Use only SAS programming.

I request help from SAS experts regarding references on applications of SAS in Cancer studies, especially Kaplan Meier Estimates,Hazard ratio and Exact Confidence Intervals.

All,
I have observed that SAS programmers in clinical trials (Phase II-IV) prefer UNIX to EG and SAS 9.1.3.
I request experts to elaborate the advantages of it.
Curious,

Thanks for the reference.
Is it necessary to apply statistical test to detect outliers in BA/BE studies for submission to USFDA?
I have found very few statisticians applying the test for 'outliers' (even if CV >30%)., some times they delete the volunteer from statistical analysis.
Experts pl offer help to resolve this issue.
Thanks

Not necessarily.
There are very few competent biostatisticians who are expert in SAS programming.
Fundamentally Biostatistics and SAS programming are different (but related to some extent) branches in Science.
Statistician has to have through knowledge of statistics (MSc/ PhD).
SAS programmers can have any basic qualification.
Very good communication can solve all FDA problems as it is the 'Lead Statistician' who has to face FDA.
It is better to learn SAS programming at the earliest for statisticians working in clinical trials.
SAS programmers with basic knowledge statistics usually shine in clinical field as SAS carries more weightage than Statistics.

Thanx a lot.
Do u have proper reference?
If yes Pl give me.
I have been using Grizzle test (statistically appropriate) for many years.
I had few analyses where Grizzle test detected carry over effect and we had to throw the data.
