Bi-factor analysis is a form of confirmatory factor analysis originally introduced by Holzinger and Swineford (Psychometrika 47:41-54, 1937). The bi-factor model has a general factor, a number of group factors, and an explicit bi-factor structure. Jennrich and Bentler (Psychometrika 76:537-549, 2011) introduced an exploratory form of bi-factor analysis that does not require one to provide an ex...

This statistical study has been carried out to examine and interpret the income types that make up sources of students. For this purpose, a data set created using 14 European countries included all for 9 variables. These have chosen as they did not contain missing each variable. Initially, factor analysis, which is method suitable purpose study, applied set. Then, principal component analysis (...

ABSTRACT We introduce a statistical method for the decomposition of data sets into planes. With the help of principal component analysis or factor analysis the data are presented in a lower-dimensional space. The factors spanning this new co-ordinate system are rotated afterwards in that sense to fulfill the idea of simple structure, extended to two dimensions. The resulting planes which are sp...

hospitalization of child is one of the most stressful events of life for parents and children. this fear and stress may affect the process of treatment. since there is no information available about the source of distress and needs of iranian parents during the inpatient care of their children, we designed a research in order to discover the main source of worries and fears among parents. in th...

The Schrödinger functional provides a valuable tool to perform non-perturbative renormalization on the lattice, in particular in a mass independent scheme. We study two different types of chirally rotated Schrödinger functional boundary conditions which have been recently proposed to retain the bulk automatic O(a) improvement of massless Wilson fermions in finite volume. We investigate the spec...

The paper concerns with the study of the modulation diversity in PSK scheme due to rotation of the signal constellation along with bit interleaving. We derive here the expressions for the Symbol Error Probability (SEP) of rotated BPSK and QPSK modulations over frequency non-selective slowly fading Nakagami-q channels. Numerical results based on moment generating function (MGF) are obtained and ...
