In addition, study design related issues that introduce bias such as description of the randomisation procedure, concealment of allocation, sample size calculations or blinding have not been addressed frequently.
The evaluation procedure is complicated, hence it is better to treat this as one independent procedure of economic allocation.
More than half the studies failed to give adequate information about their randomisation procedure and details of allocation concealment.
Step 4: The maximum downlink capacity of heterogeneous network is calculated and the procedure of hybrid frequency allocation scheme ends.
This procedure provides a curve of allocation rate as a function of the cumulative number of loci.
Most of the time this is just an administrative procedure (the 3rd year of allocation is always granted) designed to ensure that someone who is no longer working on his or her Ph.D. does not continue to be financed.
The methodological aspects assessed in reviews most often pertained to study design, appropriateness of allocation procedures, comparability of groups, validity of assessment and attrition, but only a few reviewers examined additional aspects such as quality of implementation.
The information about randomisation procedures, including the generation of allocation sequence or concealment, was under-registered and under-reported across all intervention types.
Concerning the Bias section, none of the studies provided information on the procedures for allocation concealment.
Two examples of optimum reliability allocation are used to describe the implementation procedure of CA for two-level allocation and three-level allocation respectively, and to validate preliminarily its correctness and effectiveness.
