荒野地区游憩使用量的计量经济分析AI 解读

Although outdoor recreational use fluctuates daily, this time-varying feature has received little attention by economists and statisticians. In this paper, wilderness recreational use relationships are estimated, based on daily observations over the length of a given season, by (i) traditional econometric techniques and via (ii) time series analysis procedures promoted by Box and Jenkins [3]. In applying both sets of estimated relationships for forecasting purposes, the…

分布滞后模型中参数的近似分布AI 解读

In the construction of econometric models, the need frequently arises to test the significance of coefficients whose distribution is a ratio of two normal random variables for which no statistical tables exist. In this article the distribution of such a ratio, emanating from a partial adjustment model, is empirically approximated by utilizing Monte Carlo experiments with various sample sizes. The results indicate that the standardized distribution of the ratio is positively…
