We also show that regression is unambiguously more powerful than grouping, even when the independent variable is measured with error.doi:10.1016/0304-405X(92)90033-TLys, ThomasSabino, Jowell S.ElsevierJournal of Financial EconomicsLys, T., and Sabino, J.S. (1992). Research design issues in ...

In the grouped conditions, each numerosity was organized into 2–4 clusters, each comprising a variable number of items (between 2 and 6), resulting in the following configurations: 2, 2, 1–3, 3–3, 3, 1–2, 2, 2, 2–4, 4–3, 3, 3–3, 3, 3, 1–3, 3, 3, 2–3, 3...
In other words, assign a value to a group variable gk(Tk)∈I for all Tk∈T, and so 1≤k≤|T|. This assignment can be done sequentially for each of the types: The first type will always start the first group, g1(T1)=1. Then, the second type can either be assigned to the ...

The major aim of this research is the modeling of a VM sizing scheme with task grouping. Here, the VM sizing is done using Deep-ConvLSTM, where its weight is trained with an invented FPO algorithm. Moreover, the FPO algorithm is modeled by applying the FC concept in the updated POA loca...
The variable parameters commonly used in this article are shown in Table2. There are three roles in the PBFT algorithm: client, master and replica nodes. The client is the sender of the request and is responsible for sending the request to the master node in the format < REQUEST,o,t,c>...
The article presents a study on combining nominal grouping sessions (NGS) and mail survey techniques to enhance the reliability and validity of attitudinal research while reducing biases on the part of the subjects and the researchers. The NGS technique is valuable to the marketing researchers because...
a lack of sustained and replicable research on important contemporary subjects, a tendency to dilettantism, and a failure to achieve any coherent notion of what constitutes political geographic research. Because the discipline of political geography is so amorphous and opaque to both its practitioners ...
