چکیده
ABSTRAKInvestasi emas merupakan salah satu investasi yang menjadi favorit dimasa pandemi Covid 19 seperti sekarang ini. Hal ini dikarenakan harga nilainya relatif fluktuatif tetapi menunjukkan tren peningkatan. Investor dituntut pandai dalam berinvestasi emas, mampu memprediksi peluang akan datang. Salah model peramalan data deret waktu adalah Autoregressive Integrated Moving Average (ARIMA). Model ARIMA baik digunakan pada berpola linear jika nonlinear keakuratannya menurun. Untuk mengatasi permasalahan dapat menggunakan Support Vector Regression (SVR). Pengujian linearitas adanya pola dan sekaligus sehingga kombinasi SVR yaitu hybrid ARIMA-SVR. Hasil ARIMA-SVR hasil lebih dibanding ARIMA. dibuktikan dengan nilai MAPE kecil dibandingkan Nilai sebesar 0,355 training 4,001 testing, sedangkan 0,903 4,076 testing.ABSTRACTGold investment is one of the favorite investments during pandemic as it today. This because price gold relatively volatile but shows an increasing trend. Investors are required to be smart in investing gold, able predict future opportunities. One time series forecasting models (ARIMA) model. The good for use on patterned if used accuracy decreases. To solve problem data, you can (SVR) linearity test that there and patterns at same so a combination used, namely Forecasting results using show better than evidenced by value which smaller 0.355 4.001 testing while 0.903 4.076 data.

Forecasting Inflation: Autoregressive Integrated Moving Average Model
This study compares the forecasting performance of various Autoregressive integrated moving average (ARIMA) models by using time series data. Primarily, The Box-Jenkins approach is considered here for forecasting. For empirical analysis, we used CPI as a proxy for inflation and employed quarterly data from 1970 to 2006 for Pakistan. The study classified two important models for forecasting out ...

متن کاملHybrid Support Vector Regression and Autoregressive Integrated Moving Average Models Improved by Particle Swarm Optimization for Property Crime Rates Forecasting with Economic Indicators
Crimes forecasting is an important area in the field of criminology. Linear models, such as regression and econometric models, are commonly applied in crime forecasting. However, in real crimes data, it is common that the data consists of both linear and nonlinear components. A single model may not be sufficient to identify all the characteristics of the data. The purpose of this study is to in...

In this paper, we consider a continuous-time autoregressive fractionally integrated moving average (CARFIMA) model, which is defined as the stationary solution of a stochastic differential equation driven by a standard fractional Brownian motion. Like the discrete-time ARFIMA model, the CARFIMA model is useful for studying time series with short memory, long memory and antipersistence. We inves...
