A sum of squares double exponentially weighted moving average chart

Computers & Industrial Engineering, 2011
The sum of squares double exponentially weighted moving average (SS-DEWMA) chart is proposed to improve the performance of the single SS-EWMA chart, in the detection of initial out-of-control signals. The SS-DEWMA chart uses the sum of squares statistic and it simultaneously monitors the process mean and variance in a single chart.

A double exponentially weighted moving average chart for time between events

Communications in Statistics - Simulation and Computation, 2019
tIn high quality processes when the events occur rarely, the times between events (TBE) are observed and also monitored instead of the number of events.

Double moving average control chart for exponential distributed life using EWMA

AIP Conference Proceedings, 2017
In this manuscript a new monitoring scheme has been introduced using the double moving average for the exponential distribution under the EWMA statistic. The control chart coefficients have been estimated for specific error rates of the in-control and out-of-control processes.

PERAMALAN HARGA SAHAM NVIDIA DENGAN METODE DOUBLE MOVING AVERAGE

Jurnal Ilmiah Informatika Komputer
The movement of NVIDIA's stock price greatly affects investment decisions, so accurate forecasting is very important to influence investment decisions. This research will apply the data mining process for forecasting NVIDIA stock prices using the Double Moving Average method with the application of order 2 and order 3 models.

An Evaluation of the Double Exponentially Weighted Moving Average Control Chart

Communications in Statistics - Simulation and Computation, 2010
In this article we perform a careful investigation of the double exponentially weighted moving average (DEWMA) chart performance for monitoring the process mean. We compare the performance of this chart to the usual EWMA control chart based on zero-state and worst-case average run length (ARL) measures. We also evaluate the signal resistance measure of

PENERAPAN DATA MINING DENGAN METODE DOUBLE MOVING AVERAGE UNTUK MEMPREDIKSI PENJUALAN KEDELAI

JATI (Jurnal Mahasiswa Teknik Informatika), 2023
Kedelai merupakan tanaman asli dari Daratan Cina yang telah dibudidayakan sekitar 2500 SM. Bersamaan dengan perkembangan perdagangan internasional pada awal abad ke-19. Tanaman kedelai mulai dikenal di indonesia. Penyebaran dan budidaya kedelai pada awalnya berada di sekitar pulau Jawa, kemudian menyebar ke daerah Nusa Tenggara, Bali dan pulau-pulau ...
