Skewing Methods for Variance-Stabilizing Local Linear Regression Estimation
Kiheiji Nishida
It is well-known that kernel regression estimators do not produce a constant estimator variance over a domain. To correct this problem, Nishida and Kanazawa (2015) proposed a varia…
Controllability Analyses on Firm Networks Based on Comprehensive Data
Hiroyasu Inoue
Since governments give stimulus to firms and expect the spillover effect by fiscal policies, it is important to know the effectiveness that they can control the economy. To clarify…
Analyses of Aggregate Fluctuations of Firm Network Based on the Self-Organized Criticality Model
Hiroyasu Inoue
This study examine the difference in the size of avalanches among industries triggered by demand shocks, which can be rephrased by control of the economy or fiscal policy, and by u…
On possible origins of trends in financial market price changes
Ryo Murakami, Tomomichi Nakamura, Shin Kimura +2
We investigate possible origins of trends using a deterministic threshold model, where we refer to long-term variabilities of price changes (price movements) in financial markets a…
Constructing directed networks from multivariate time series using linear modelling technique
Toshihiro Tanizawa, Tomomichi Nakamura, Fumihiko Taya +1
We describe a method to construct directed networks from multivariate time series which has several advantages over the widely accepted methods. This method is based on an informat…
All-sky Galactic radiation at 45 MHz and spectral index between 45 and 408 MHz
Andres E. Guzmán, Jorge May, Hector Alvarez +1
Aims: We study the Galactic large-scale synchrotron emission by generating a reliable all-sky spectral index map and temperature map at 45 MHz. Methods: We use our observations, th…
