    I measured the drug response (anticoagulation, via a measurement called INR) every day after my patients took the anticoagulant called warfarin. So I have collect a great many of continuous quantitative data called INR. Everyday my patient would be extant venous blood, which were used to measure the INR. So I have INRs data on day 1, day 2, ..., day 35. As you may guess, I want to plot the INR and the time (day X), in the form of the mean and confidence interval of INR data. This is what I want.
    For that the approach I outlined in post #7 is indeed relevant, and using regress, margins, and marginsplot to attempt to accomplish this is incorrect.

    I recommend you start a new topic beginning with the quoted paragraph, and with an appropriate subject about producing a plot. That may draw suggestions of better technique than mine, or perhaps of user-written commands from SJ or SSC that directly accomplish what you seek, from members with expertise in graphics who have not been following this topic.

    You may find the user-written command ciplot to be helpful. Look at search ciplot for details.

      Contrary to previous advices to avoid it , you seem to persist (as in #14) in sharing snapshots of copyright material.

      Please act according to the principles underlined in the FAQ.

      Please, I'll repeat it again: do not share copyright material.

      Thank you in advance for understanding it.
      Best regards,

        OK. I have referred to the name of the textbook and author. Thanks for their great works.

          That difference sounds like it is just your regression coefficent. Can you clarrify why you think that is not the case?

            This is not about giving credit, but about the legal consequences of sharing copyrighted material. So providing the title of the book and the author and thanking him does not help.
