Age differences in the variability and distribution of sleep spindle and rapid eye movement densities. by Kevin R Peters, Laura B Ray, Stuart Fogel, Valerie Smith, Carlyle T Smith

“…Although age differences were observed in the degree of absolute variability (older adults had significantly larger variances than young adults for sleep efficiency and time spent awake after sleep onset), a similar pattern was also observed within the two age groups: the four sleep measures with the lowest degrees of relative variability were the same and included time spent in REM and Stage 2 sleep, total sleep time, and sleep efficiency. …”

Modeling the Public Transport Networks: A Study of Their Efficiency by Mary Luz Mouronte-López

“…We have found that this process may be appropriately explained by a generalized linear model (GLM) using local, global, and quasilocal similarity indexes as explanatory variables. In modeling, the response variable was described by a binomial probability density function, and the logit function was used as a link function. …”
