We apply the object-oriented robust factor analysis R package robustfa to the 28 financial indicators of the 100 listed companies in China’s Chinese Securities Index (CSI) 100 index in the first quarter of 2013. First of all, according to the size of the data, we automatically choose a robust estimator, the robust Ogk estimator. By the Mahalanobis distances which are computed by the robust Ogk ...

background the choice of what parameters are needed for the diagnosis of metabolic syndrome (mets) has been criticized due to the lack of an actual “gold standard” diagnostic test even in adults. this problem seems to be greater in children and adolescents. objectives stability assessment of factor structure underlying metabolic syndrome (mets) components from childhood to adolescence in a pane...

one priority of planning at the regional level is to recognize the system of residence and particularly its urban system. one of the features of urban system in each area or country is the way of population distribution between the cities of these areas which is called city distribution size. in functional analysis of mazandaran province 41 development indexes of educational, cultural, social, ...

abstract     in order to study the relationships among seed yield and its components in nigella sativa, path coefficient and factor analysis was done using some agro- morphological traits of 21 different genotypes. genotypes were evaluated using a completely randomized design with four replications in ardestan university research farms. there was a high and positive correlation between seed yie...

seeds of 200 accessions of alfalfa (medicago sativa l.) were provided from iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of hamadan, iran during 2009 to 2010. the data were collected and analyzedfor plant height, stem number, leaf stem ra...

Harmonically rich sounds have been shown to be processed more efficiently by the human brain compared to single sinusoidal tones. To control for stimulus complexity as a potentially confounding factor, tones and equally complex spectrally rotated sounds, have been used in the present study to investigate the role of the overtone series in sensory auditory processing in non-musicians. Timbre dif...

This paper demonstrates that piecewise, rotated explicit curves are flexible enough for 2–D modeling applications such as font design. Their use simplifies many operations such as scan conversion, point classification, and curve intersection.

We proposed a rotated character recognition method using eigen-subspace characterized multiple projection and simple projection. Then the multiple projections showed a higher accuracy at low dimensions than a simple projection for alphanumeric 62 categories. This time, we applied it for the first class of Japanese Industrial Standard (JIS) Kanji set which includes 2,965 categories. As the resul...
