Thank you once more for the vidoes. Is it possible to include a video regarding LSMean and how it differs from the arithmetic mean? When should we think about LSMean? ....

Does weighted mean difference have standard deviation?

Yes, you can also calculate weighted SD.

@@tilestats is it possible to calculate the weighted SD from only the values as shown: Participants in the ezetimibe and statins group had lower LDL-C (mean difference -13.14 mg/dL; 95% CI -16.83 to -9.44; p= 0.00001)?

Is this at all related to a moving average (from time series analysis)?
@tilestats
@tilestats 2 жыл бұрын
No, but you can have a weigthed moving average, where, for example, more recent time points get a greater weight.
