For compatibility with S-PLUS, the data sets stack.x, a matrix with the first three (independent) variables of the data frame, and stack.loss, the numeric vector giving the fourth (dependent) variable, are provided as well.
,S-PLUS的兼容性,数据设置stack.x前三(独立)的数据框的变量的矩阵,和stack.loss,给第四条(供养)变量的数值向量,以及提供。

详情----------Details----------
“Obtained from 21 days of operation of a plant for the oxidation of ammonia (NH3) to nitric acid (HNO3). The nitric oxides produced are absorbed in a countercurrent absorption tower”. (Brownlee, cited by Dodge, slightly reformatted by MM.)
“从一个工厂的运作21天获得的氨氧化(新罕布什尔州3)硝酸(硝酸3)。所产生的氮氧化物在逆流吸收塔吸收“。 (布朗利,由道奇专利,稍微格式化的MM。)
Air Flow represents the rate of operation of the plant. Water Temp is the temperature of cooling water circulated through coils in the absorption tower. Acid Conc. is the concentration of the acid circulating, minus 50, times 10: that is, 89 corresponds to 58.9 per cent acid. stack.loss (the dependent variable) is 10 times the percentage of the ingoing ammonia to the plant that escapes from the absorption column unabsorbed; that is, an (inverse) measure of the over-all efficiency of the plant.
Air Flow代表工厂的运作率。 Water Temp是通过线圈在吸收塔循环冷却水的温度。 Acid Conc.是酸循环的浓度,再减去50,10倍,即:89对应酸58.9%。 stack.loss(因变量)未吸收的吸收列逃脱到工厂,从迁入氨的比例是10倍,也就是说,所有的工厂效率的(反)措施。
