Ben Nichols, a media relations manager for the World Anti-Doping Agency, said that WADA's code "leaves some flexibility in terms of public disclosure" for provisional suspensions, allowing for variation between each sport's governing bodies.
Next, the policy effect is imposed to be constant across quarters within a year, but allowing for variation between years by introducing year specific dummies for the policy period.
We show how data from unadmixed and admixed populations can be combined to estimate these ancestry-specific allele frequencies within the admixed population under study, allowing for variation between allele frequencies in unadmixed and admixed populations.
The use of a random effects model allows for variation between the studies and can be used when the source of variation cannot be identified [22], [23].
This allows for variation between carriers from the same family without modelling their dependence explicitly.
The CMH test takes account of the hospital clustering effect and allows for variation between the strata in the underlying rates.
Our other models (2, 4, 5, 6) did allow for variation in DUP between neighbourhoods, and hence provided estimates of the area-level variability.
We used a discrete time version of the Cox model (with a complementary log log link function, an offset to allow for variation in the time between visits and robust standard errors) 26 because liver fibrosis could only be assessed at each cohort visit.
The sample size for this study needs to be increased to allow for variation in self-harm rates between villages (i.e. the randomisation unit).
Although previous studies focus specifically on the "time of the day" effect on bidding behavior by conducting auctions throughout the day (Demont et al., 2012, 2013a, 2013b; Morawetz, De Groote, and Chege, 2011; Hoffman et al., 1993; Menkhaus et al., 1992), we use the 2-hour difference between auctions to allow for variation in hunger, not to measure "time of day" impact.
