Prediction in a Trivariate Normal Distribution via Two Order Statistics
In this paper, assuming that (X, Y1, Y2)T has a trivariate normal distribution, we derive the exact joint distribution of ( X, Y(1), Y(2))^T, where Y(1) and Y(2) are order statistics arising from (Y1, Y2)T . We show that this joint distribution is a mixture of truncated trivariate normal distributions and then use this mixture representation to derive the best (nonlinear) predictiors of X...
متن کاملasymptotic property of order statistics and sample quntile
چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولSecond-order statistics of natural images
Assuming adaptation of the visual cortex to its environment, we analyse the invariance found in natural images to explain the selective response of visual cortical neurons. We argue that the invariant structure of images can be formally expressed by dot-products. Utilizing the specific structure of the proposed model we show how non-linear functions can be learned efficiently from natural image...
متن کاملSecond-order Linearity of Wilcoxon Statistics *
The rank statistics Sn(t) = 1 n ∑n i=1 ciRi(t) (t ∈ R), with Ri(t) being the rank of ei−txi, i = 1, . . . , n and e1, . . . , en being the random sample from the basic distribution with the cdf F , are considered as a random process with t in the role of parameter. Under some assumptions on ci, xi and on the underlying distribution, it is proved that the process {Sn( t √n)− Sn(0)− ESn(t), |t|2 ...
متن کاملSynchronization from Second Order Network Connectivity Statistics
We investigate how network structure can influence the tendency for a neuronal network to synchronize, or its synchronizability, independent of the dynamical model for each neuron. The synchrony analysis takes advantage of the framework of second order networks, which defines four second order connectivity statistics based on the relative frequency of two-connection network motifs. The analysis...
