Patients were randomized (random option in Microsoft Excel software, Qumak Secom SA, Warsaw, Poland) to atorvastatin (40 mg, in the evening) or placebo group.
If the random option is chosen, then it is not possible to predict which values of that range are going to be selected.
Through this parallel internal action simulation mechanism, the agent will not select a random option but the one which has the strongest valuated feeling.
Upon opening the app, users will be able to connect to Facebook and join a room with any of their Facebook friends who have also downloaded the app, or can select a random option where they are put in a room with three other viewers.
The method was performed using close-neighbor interchange with a random option and with 500 bootstrap repetitions.
The "random" option was used to specify nursing home and resident frailties in the time to first hospitalization and time between hospitalizations models, respectively.
Taking heterogeneity as random (option ii) is common practice in meta-analysis [ 6, 15], and this is also our preferred approach over option (i) for the reasons stated at the end of the Methods section.
Summary statistics were pooled by using a meta-analysis with a random-effects model to account for differences between cohorts and methods (by using the random option for the Stata command metan).
To deal with remaining redundant haplotypes, one tree from the 15,000 fully resolved trees sampled from the posterior distribution by MrBayes was selected for each run using the "random" option in Phylomapper.
Since we have fixed within-study variances, we need to tell proc mixed to incorporate this appropriately; this can be accomplished by using a weight, w i = 1 / σ i 2. The random option induces a random effect (here study) with associated variance component τ, which is estimated.
