Python uses support vector machine regression (SVR) model to analyze power consumption and predict power consumption
Original link: http://tecdat.cn/?p=23921 This paper describes the process of training support vector regression model, which is used to predict power consumption based on several weather variables, an hour of the day, and whether the day is weekend / holiday / home working day or ordinary working day. Fast description of support vector machine Support vector […]

R language arima-garch volatility model predicts the daily return time series of apple in the stock market
Original link:http://tecdat.cn/?p=23934 introduction In this paper, we will try to find a suitable GARCH model for Apple’s daily return. Volatility modeling requires two main steps. Specify a mean equation (e.g. ARMA, AR, Ma, ARIMA, etc.). Establish a volatility equation (such as GARCH and arch, which were first developed by Robert Engle). To do (1), you […]
