We construct geometric shrinkage priors for Kählerian signal filters. Based on the characteristics of Kähler manifold, an algorithm for finding the superharmonic priors is introduced. The algorithm is efficient and robust to obtain the Komaki priors. Several ansätze for the priors are also suggested. In particular, the ansätze related to Kähler potential are geometrically intrinsic priors to th...

In this paper, we study a first order random coefficient autoregressive model with Laplace distribution as marginal. A random coefficient moving average model of order one with Laplace as marginal distribution is introduced and its properties are studied. By combining the two models, we develop a first order random coefficient autoregressive moving average model with Laplace marginal and discus...

This paper presents an empirical analysis of the Russian market of mergers and acquisitions (the largest market for corporate control in Central and Eastern Europe) in 2003–2012 in terms of the total volume and value of the merger and acquisition deals of the holding companies. This analysis allowed for the conclusion that, to assess and forecast the integration activity of holding companies, t...

Overstock is a problem that often occurs in inventory management, the factor are number of sales and expired date. CV.A distributor company for goods.

Research results showed forecast SNACK X using WMA method July 2021 1662, while ES 1697. After performed f...

One of the most powerful tools in quality control is the statistical control chart. First developed in the 1920's by Walter Shewhart, the control chart found widespread use during World War II and has been employed, with various modifications ever since. The drawbacks to multivariate charting schemes is their inability to identify which variable was the source of the signal. The multivariate ex...

Compression and differencing techniques can greatly improve storage and transmission of files and file versions. Since files are often transported across machines with distinct architectures and performance characteristics, compressed data should be encoded in a form that is portable and efficient to decode. This paper describes the Vcdiff encoding format for differencing and compression data a...
