4、省生产总值每增加1亿元,财政预算总收入增加0.176124亿元。(2)当x=32000时,①进行点预测,由上可知Y=0.176124X—154.3063,代入可得:Y=Y=0.176124*32000—154.3063=5481.6617②进行区间预测:-先由Eviews分析:XY Mean 6000.441 902.5148 Median 2689.280 209.3900 Maximum 27722.31 4895.410 Minimum 123.7200 25.87000 Std.Dev. 7608.021 1351.009 Skewness 1.432519 1.663108 Kurt
