For a two-sided 95% prediction interval, the critical t value for n = 8 is t = 2.3646, as might be found using the Excel function = TINV(1 − confidence Level, n − 1). The prediction interval extends from X¯−t(Standarderrorforprediction)=8.125−(2.3646)(3.12786)=0.729 ...
interval="prediction" 代表预测区间，这个区间是一个包含新观测值真实值的区间范围。不同于置信区间，...

We predict a 5-minute Interval line chart for intraday traders and provide a time scale below the chart to predict how the market will unfold in the next trading from a specific point of time with uncanny accuracy using Mathematical Time Cycles. This page is updated until Mar 18, 2025. ...
Remarkably, the CatB model exhibited the best performance on both the training and validation cohorts, yielding an AUC of 0.9614 (95% confidence interval (CI): 0.9377–0.9813), an accuracy of 0.9085 (95% CI: 0.8708–0.9459), a recall of 0.9059, a precision of 0.8930, and an F1 score ...
I have been able to find the required CI's but I cannot figure out how to calculate a 95% prediction interval for what the mean would be of an additional sample of 10. I have examples with data sets and I have checked online and found information with data sets. But this is all I...
