چکیده
Forecasting is an essential analytical tool used to make future predictions based on preliminary data. However, the use of small sample sizes during analysis provides inaccurate results, known as asymptotic forecasting. Therefore, this study aims to analyze the unemployment rate of educated people in Indonesia using the bias-corrected forecasting bootstrap technique. Data were collected from a total of ۳۰ time series of educated unemployed from ۲۰۱۵ to ۲۰۱۹ using the bias-corrected bootstrap technique and determined using the interval prediction method. The bootstrap replication used is at intervals of ۱۰۰, ۲۵۰, ۵۰۰, and ۱۰۰۰. The results obtained using the R program showed that the bootstrap technique provides consistent forecasting results, better accuracy, and unbiased estimation. Moreover, the results also show that for the next ۱۰ periods, the number of educated unemployed people in Indonesia is projected to decline. The bootstrap coefficient also tends to decrease with an increase in the number of replications, at an average of ۰.۹۵۸. The interval prediction is also known to be smooth, along with a large number of bootstrap replications.کلیدواژه ها
