On the Johnson - Neyman
نویسنده
چکیده
The Johnson-Neyman technique is a statistical tool used most frequently in educational and psychological applications. This paper starts by briefly reviewing the JohnsonNeyman technique and suggesting when it should and should not be used; then several different modifications and extensions of the Johnson-Neyman technique, all of them conceptually simple, are proposed. The close relation between confidence intervals and regions of significance of the Johnson-Neyman type is pointed out. The problem of what . to do when more than two groups are being compared is considered. The situation of more than one criterion variable is also considered.

Performance of the Neyman-Pearson Receiver for a Binary Thermal Coherent State Signal
The performance of the quantum NeymanPearson receiver for a binary coherent state signal in the presence of thermal noise is numerically investigated. To see the detection sensitivity of the quantum Neyman-Pearson receiver, its receiver operating characteristics (ROC) are numerically obtained. The performance limit of the quantum Neyman-Pearson receiver is directly computed when the false alarm...
متن کاملANCOVA for nonparallel slopes: the Johnson-Neyman technique.
The Johnson-Neyman (JN) procedure, as originally formulated (Stat Res Mem, 1 (1936) 57-93), applies to a situation in which measurements on 1 dependent (response) variable, X, and 2 independent (predictor) variables, Z1 and Z2, are available for the members of 2 groups. The expected value of X is assumed to be a linear function of Z1 and Z2, but not necessarily the same function for both groups...
متن کاملGeneration of the Typical Cell of a Non-poissonian Johnson-mehl Tessellation
We consider Johnson-Mehl tessellations generated by stationary independently marked (not necessarily Poissonian) point processes in d-dimensional Euclidean space. We rst analyze the Palm distribution of the thinned point process which coincides with the family of nuclei of non-empty Johnson-Mehl cells. This yields quite a general scheme for the construction of the typical Johnson-Mehl cell base...

Abstract The school culture is a linking agent that teachers, parents and managers need it to coordinate their local traditions and styles. The aim of this research Was to investigate the relationship between school culture and academic achievement of students by the moderating role of school size. The present study was conducted by correlation method. All the teachers in the Primary schools in...
متن کاملCAHOST: An Excel Workbook for Facilitating the Johnson-Neyman Technique for Two-Way Interactions in Multiple Regression
When using multiple regression, researchers frequently wish to explore how the relationship between two variables is moderated by another variable; this is termed an interaction. Historically, two approaches have been used to probe interactions: the pick-a-point approach and the Johnson-Neyman (JN) technique. The pick-a-point approach has limitations that can be avoided using the JN technique. ...
