90% CI Calculation

SaranyaSundar — Wed, 20 Mar 2019 04:35:58 GMT

My data set contain variables TIME, TREATMENT and DATA. How do i calculate two one sided Confidence interval for this data using SAS? Can anyone help?

Can you give a bit more detail - maybe some dummy data to help us solve the problem?

Time Treatment Data

0 T 1

15 T 3

25 T 2

40 T 2

55 T 3

0 R 1

15 R 2

25 R 3

40 T 1

55 T 3

I need to first calculate the T/R Ratio and then the T/R ratio values must be used to find 90% CI.

Thanks for the help.

What is the T/R ratio? How is it computed?

How is TIME and DATA used?

T/R Ratio is the Test/Reference ratio. The values mentioned in Data will be used to calculate T/R Ratio

I'm afraid that doesn't really answer the question, as far as I can understand it. Show us the calculation.

Also, please state clearly how TIME is used, since you originally asked for confidence intervals on TIME as well.
