Estimation and inference for area-wise spatial income distributions from grouped data [article]

Shonosuke Sugasawa, Genya Kobayashi, Yuki Kawakubo
2019 arXiv   pre-print
In this work, we develop an effective method for the simultaneous estimation and inference for area-wise spatial income distributions taking account of geographical information from grouped data.  ...  Based on the multinomial likelihood function for grouped data, we propose a spatial state-space model for area-wise parameters of parametric income distributions.  ...  Acknowledgements This work was supported by JSPS KAKENHI Grant Numbers 18K12754, 18K12757, 19K13667 and Japan Center for Economic Research.  ...

Sparse estimation of huge networks with a block-wise structure

Francesco Moscone, Elisa Tosetti, Veronica Vinciotti
2017 Econometrics Journal  
While requiring a-priori information on the block structure, for example given by the hierarchical structure of data, our approach can be adopted for estimation and prediction using very large panel data  ...  Networks with a very large number of nodes appear in many application areas and pose challenges to the traditional Gaussian graphical modelling approaches.  ...  for estimating spatial weights matrices in the context of very large panel data.  ...

A memory-free spatial additive mixed modeling for big spatial data [article]

Daisuke Murakami, Daniel A. Griffith
2019 arXiv   pre-print
This study develops a spatial additive mixed modeling (AMM) approach estimating spatial and non-spatial effects from large samples, such as millions of observations.  ...  To overcome this limitation, this study develops a fast AMM with the estimation of spatial structure in residuals and regression coefficients together with non-spatial effects.  ...  Acknowledgement This study is funded by the JSPS KAKENHI Grant Numbers 17K12974 and 18H03628.  ...

A microsimulation of spatial inequality in energy access: A Bayesian multi-level modelling approach for urban India [article]

A. P. Neto-Bradley
2021 arXiv   pre-print
Limited data exists on the spatial distribution of energy use in Indian cities, particularly amongst low-income households, and most quantitative studies focus primarily on the effect of economic determinants  ...  A microsimulation approach is proposed, using publicly available data and a Bayesian multi-level model to account for effects of current cooking practices, local socio-cultural context, and spatial effects  ...  The authors are grateful to Luke Archer at the Leeds Institute for Data Analytics, University of Leeds, for advice on generating synthetic populations using R.  ...
