Based on the national sample city’ s TV ratings data which is from Monday to Sunday,the article gives out the trend analysis. Under the condition of the same trend,the data of Thursday are analyzed in time series modeling and after using the second-order difference method to make the original non-stationary time series to become stationary,ARIMA model was made. |
