An efficient and convenient procedure has been described for one-pot multi-component synthesis of tetrahydrobenzo[b]pyrans known as 2-amino-7,7-dimethyl-5-oxo-4-phenyl-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile which can be obtained from the react

AstroSat/UVIT Study of the open cluster NGC 2818: Membership, Blue Stragglers, Yellow Stragglers, and Planetary Nebula
Autor: Sharmila Rani, Annapurni Subramaniam, Gajendra Pandey, N. K. Rao
We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster (OC) NGC 2818 that has a Planetary nebula (PN) within the field. We explore whether the PN is a member of the cluster using images taken from the Ultra-vi

A Weighted Composite Likelihood Approach to Inference from Clustered Survey Data Under a Two-Level Model
Autor: Laura Dumitrescu, Wei Qian, J. N. K. Rao
Publikováno v: Sankhya A. 83:814-843
Two-level models are widely used for analysing clustered survey data with the design structure matching the model hierarchy. Hypothesis testing on model parameters is studied, using a weighted composite likelihood approach that takes account of the s

On Making Valid Inferences by Integrating Data from Surveys and Other Sources
Autor: J. N. K. Rao
Publikováno v: Sankhya B. 83:242-272
Survey samplers have long been using probability samples from one or more sources in conjunction with census and administrative data to make valid and efficient inferences on finite population parameters. This topic has received a lot of attention mo

Bayesian Empirical Likelihood Inference with Complex Survey Data
Autor: J. N. K. Rao, Malay Ghosh, Changbao Wu, Puying Zhao
Publikováno v: Journal of the Royal Statistical Society Series B: Statistical Methodology. 82:155-174
Summary We propose a Bayesian empirical likelihood approach to survey data analysis on a vector of finite population parameters defined through estimating equations. Our method allows overidentified estimating equation systems and is applicable to bo

Hierarchical Bayes small‐area estimation with an unknown link function
Autor: Tatsuya Kubokawa, J. N. K. Rao, Shonosuke Sugasawa
Publikováno v: Scandinavian Journal of Statistics. 46:885-897
Area-level unmatched sampling and linking models have been widely used as a model-based method for producing reliable estimates of small-area means. However, one practical difficulty is the specification of a link function. In this paper, we relax th
