Convergence in Total Variation to a Mixture of Gaussian Laws

open access: yesMathematics, 2018
It is not unusual that Xn⟶distVZ where Xn, V, Z are real random variables, V is independent of Z and Z∼N(0,1). An intriguing feature is that PVZ∈A=EN(0,V2)(A) for each Borel set A⊂R, namely, the probability distribution of the limit VZ is a ...

Scaling Analysis of Multilevel Polar Coded Modulation

open access: yesIEEE Access, 2019
In this paper, we analyze and prove the capacity-achieving property of the equivalent asymmetric channels of multilevel polar-coded modulation in view of the scaling assuming regime, which employ some techniques of symmetric channels.

A Class of Association Measures for Categorical Variables Based on Weighted Minkowski Distance

open access: yesEntropy, 2019
Measuring and testing association between categorical variables is one of the long-standing problems in multivariate statistics. In this paper, I define a broad class of association measures for categorical variables based on weighted Minkowski distance.

Principal Component Analysis (PCA) and hierarchial clustering in tobacco (Nicotiana tabacum L.) for yield and yield attributing traits

open access: yesElectronic Journal of Plant Breeding, 2023
Multivariate statistical analysis techniques like Principal Component Analysis (PCA) and heirarchial clustering were used to evaluate Genetic diversity among 246 genotypes of Tobacco for six major yield and yield-related traits.

DOES PREOPERATIVE TIBIAL TUBEROSITY – TROCHLEAR GROOVE DISTANCE EFFECT ON POSTOPERATIVE PATELLAR INSTABILITY IN THE PATIENTS WITH KNEE ARTHROPLASTY DUE TO MEDIUM-ADVANCED KNEE OSTEOARTHRITIS?

open access: yesSanamed, 2020
Objectives: Determining tibial tubercle-trochlear groove distance range as measured before the operation in the patients to whom total knee prosthesis will be applied due to mid to advanced level of osteoarthritic and seeing the post-operative variations

Operational Quantum Average-Case Distances [PDF]

open access: yesQuantum, 2023
We introduce distance measures between quantum states, measurements, and channels based on their statistical distinguishability in generic experiments.

Total Variation Distance for Poisson Subset Numbers

open access: yesAnnals of Combinatorics, 2006
Let n be an integer and A0,..., A k random subsets of {1,..., n} of fixed sizes a0,..., a k , respectively chosen independently and uniformly. We provide an explicit and easily computable total variation bound between the distance from the random variable

Topological Structures on DMC Spaces †

open access: yesEntropy, 2018
Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet X and output alphabet Y can be naturally endowed with the quotient of the Euclidean topology by the equivalence ...

On the speed of convergence to stationarity of the Erlang loss system [PDF]

open access: yes, 2009
We consider the Erlang loss system, characterized by $N$ servers, Poisson arrivals and exponential service times, and allow the arrival rate to be a function of $N.$ We discuss representations and bounds for the rate of convergence to stationarity of the

Multi-Epoch VLBA Observations of the Compact Wind-Collision Region in the Quadruple System Cyg OB2 #5 [PDF]

open access: yes, 2012
We present multi--epoch VLBA observations of the compact wind collision region in the Cyg OB2 #5 system. These observation confirm the arc-shaped morphology of the emission reported earlier.
