We study house allocation problems introduced by L. Shapley and H. Scarf (1974, J. Math. Econ.1, 23 28).
However, retrospective, observational data such as those of the LIVE-DE study are prone to bias because of no random treatment allocation, and selection bias introduced by only being able to document those with a complete follow-up.
This implies that nonrandomized studies should follow the remaining methodological tools usually employed in randomized trials and that the uncertainty introduced by the allocation mechanism should be explicitly reported and, if possible, quantified.
The out-band relaying can provide certain gains over the in-band relaying scheme: a throughput gain in case of non-adjacent carrier allocation because of the overhead introduced by the in-band relaying operation and the lower retransmission delay as explained in Section 3.2.1.
Possibly, the importance of this item was not appreciated by abstract authors because the paper by Schulz, demonstrating the bias introduced by open allocation was only published in 1995, i.e. after conclusion of our abstract submission period studied [ 33].
For example, it has been recommended that CEA be conducted from a societal perspective, and that a lifetime horizon be employed, since only these approaches avoid allocation biases that may be introduced by a narrower approach.
However, the results also point out the importance of the spatial stream allocation algorithm and the high overheads introduced by the CSI acquisition procedure.
It is possible that some of this effect is a result of bias introduced by incomplete concealment of allocation or unblinded outcome assessment, as opposed to a true effect of the video decision aid.
The aim of blinding is to reduce the risk of unrecognised bias being introduced by participants when they are aware of intervention allocation.
This letter proposes a novel Hybrid Slot Allocation Mechanism (HSAM) to solve the high collision problem among four Access Categories (ACs) introduced by IEEE 802.11e EDCA protocol.
