    Time-weighted averages using trapezoid rule

    Thank you for your help. I think the % of time with elevated A1c would be useful, and way less difficult. In terms of vascular damage, my study is in children and none of them have these complications yet. I really appreciate your time!

    Time-weighted averages using trapezoid rule

    My sample size is 36 participants and the dependent scale is scaled scores (norm mean=10), standard score (norm mean=100), or seconds top complete a task.

    Time-weighted averages using trapezoid rule

    Yes, you are right. This is my first time posting on forums, so I thank you for your patience. For the time-weighted HbA1c, I don't think I will need to control for anything else. Thank you!

    Time-weighted averages using trapezoid rule

    Thank you for your reply! I am hoping to get time weighted averages for each child to use as a predictor for my outcomes (performance on cognitive assessment). Yes, I am expecting some change over time, and did not provide any intervention. Regarding controlling for age, I am not sure. HbA1c...

    Time-weighted averages using trapezoid rule

    I am completing my dissertation with kids with type 1 diabetes. I have clinical data available (a blood test) about general diabetes control. Each kid will have different time periods between blood draws as well as different number of total time this is being monitored. I have seen in other...
