SpletFor two independent rolls of a fair die, let X denote the value rolled the first time and Y denote the value rolled the second time. The random variables X and Y are independent, and they have the same distribution. Consequently cov.X;Y/ D0, and var.X/Dvar.Y/.

Explanatory variables were time (subtracting time of death from meas-urement time of VS, divided by 36) and opioid use. Mean difference (MD) of time represented the slope per hour of VS values. First, we analyzed the associations between VS per hour and time using a linear mixed model (LMM) with random intercepts and slope over time.
