Revisiting Toeplitz and Hankel random matrices via -convergence of circulant-type matrices
Arup Bose, Pradeep Vishwakarma
We establish the joint -convergence of a random circulant matrix and a specific deterministic diagonal matrix. We also show that the empirical spectral distributions of skew-cir…
Measuring spatial association and testing spatial independence based on short time course data
Divya Kappara, Arup Bose, Madhuchhanda Bhattacharjee
Spatial association measures for univariate static spatial data are widely used. When the data is in the form of a collection of spatial vectors with the same temporal domain of in…
Assessing bivariate independence: Revisiting Bergsma's covariance
Divya Kappara, Arup Bose, Madhuchhanda Bhattacharjee
Bergsma (2006) proposed a covariance (X,Y) between random variables X and Y. He derived their asymptotic distributions under the null hypothesis of independence between X and Y.…
Modelling COVID-19-III: endemic spread in India
Madhuchhanda Bhattacharjee, Arup Bose
A disease in a given population is termed endemic when it exhibits a steady prevalence. We address the pertinent question as to what extent COVID-19 has turned endemic in India. Th…
Matrices With Independent Entries
Arup Bose, Priyanka Sen
Let be the (unscaled) sample covariance matrix where is a real matrix with independent entries. It is well known that if the entries of are independen…
Some patterned matrices with independent entries
Arup Bose, Koushik Saha, Priyanka Sen
Patterned random matrices such as the reverse circulant, the symmetric circulant, the Toeplitz and the Hankel matrices and their almost sure limiting spectral distribution (LSD), h…
