Functional principal component analysis (FPCA) has played an important role in the development of functional time series analysis. This note investigates how FPCA can be used to analyze cointegrated and proposes a modification as novel statistical tool. Our modified not only provides asymptotically more efficient estimator cointegrating vectors, but also leads FPCA-based tests for examining ess...
Introduction: Mutations in the BRCA1 gene are major risk factors for breast and ovarian cancers. However, the relationship between some BRCA1 mutations and cancer risk remains largely unknown. Cancer risk predictions could be improved by evaluation of the impairment degree in the BRCA1 functions due to a specific mutation. This study aimed to assess the functional effect of a novel variant (Glu...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
With the advance of modern technology, more and more data are being recorded continuously during a time interval or intermittently at several discrete time points. They are both examples of “functional data”, which have become a commonly encountered type of data. Functional Data Analysis (FDA) encompasses the statistical methodology for such data. Broadly interpreted, FDA deals with the analysi...
won{gil park [won{gil park, j. math. anal. appl., 376 (1) (2011) 193{202] proved the hyers{ulam stability of the cauchy functional equation, the jensen functional equation and the quadraticfunctional equation in 2{banach spaces. one can easily see that all results of this paper are incorrect.hence the control functions in all theorems of this paper are not correct. in this paper, we correctthes...
the phytoplankton structure and dynamics were analysed in relation to abiotic variables inpaso de las piedras reservoir, argentina. phytoplankton driving forces were explored using a functionalapproach. a total of 15 functional groups were identified among which d, p, h1, f, j and c were the mostimportant. a canonical variate analysis indicated that the categorization of the species in function...
ectomyelois ceratoniae zeller (lepidoptera.: pyralidae), is the key pest of pomegranate in iran. trichogramma wasps could be used as effective agents of biological control that can also be used effectively in ipm programs. the effect of host density on parasitism of trichogramma brassicae was studied by exposing densities of 4, 8, 10, 20, 40, 60, 80 and 120 eggs of factitious host (sitotroga ce...
