Abstract

In this paper, the time series model and grey prediction model are established, and the stability of ARIMA model is tested by difference test, and the prediction is carried out. The prediction result is taken as the upper interval of the prediction interval, and the grey prediction result is taken as the lower interval of the prediction interval. The time series and grey prediction models are established respectively. Secondly, this paper establishes Pearson correlation coefficient model to analyze the relationship between lexical attributes and the percentage of difficulty pattern attempt scores. Three indicators are selected for the attributes of words: word complexity, letter frequency and the number of repeated letters, which are analyzed by taking the average number of attempts. It is found that these three indicators are significantly correlated with the number of attempts, the number of letter repetition and word complexity are positively correlated with the average number of attempts, and the letter frequency is negatively correlated with the average number of attempts.
