A comparison of conventional linear regression methods and neural networks for forecasting educational spending 总被引:1,自引:0,他引:1
This study presents an application of neural network methods for forecasting per pupil expenditures in public elementary and secondary schools in the United States. Using annual historical data from 1959 through 1990, forecasts were prepared for the period from 1991 through 1995. Forecasting models included the multivariate regression model developed by the National Center for Education Statistics for their annual Projections of Education Statistics Series, and three neural architectures: (1) recurrent backpropagation; (2) Generalized Regression; and (3) Group Method of Data Handling. Forecasts were compared for accuracy against actual values for educational spending for the period. Regarding prediction accuracy, neural network results ranged from comparable to superior with respect to the NCES model. Contrary to expectations, the most successful neural network procedure yielded its results with an even simpler linear form than the NCES model. The findings suggest the potential value of neural algorithms for strengthening econometric models as well as producing accurate forecasts. [JEL C45, C53, I21] 相似文献

In the period since 1944 English primary education has been subject to recurring criticism. Official enquiries, surveys of attainment, individual causes-célèbres and the pronouncements of pundits have drawn attention to purported 'rises' The paper discusses the background, procedures and findings of the earliest of the post-war official enquiries – an unpublished and previously uncited investigation by the Central Advisory Council for Education (England). 相似文献

This article examines the effects of intensive phonological‐awareness (PA) instruction for kindergarten English learners. One intact kindergarten class was provided 300 minutes of intensive instruction in PA. Results indicate that students who received intervention made significant growth in word reading when compared to a cohort of kindergarten students who received general kindergarten instruction. The article also discusses ability‐group differences in performance among high‐, middle‐, and low‐performing students and the implications of these findings for instructional practice. 相似文献
