最近在做化学反应动力学的线性拟合分析,经人推荐用了R软件,但是返回的结果让我头疼(呵呵本人学化学的,对统计真是一窍不通),请xdjm们帮帮忙,帮我破译一下结果吧,结果说明什么问题呢?可能对各位统计专业的高人们只是小菜一碟,但是对我可是莫大的帮助啊。无以为报,只能在这里谢谢大伙儿了!!
是一元线性回归,方程类似Cp=Cs*x+C,返回的结果如下:
Call:
lm(formula = Cp ~ Cs, data = forbes)
Residuals:
Min 1Q Median 3Q Max
-113.68 -75.34 -45.26 71.63 182.90
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 1.642 42.711 0.038 0.97
Cs 280.565 18.202 15.414 2.85e-09 ***
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Residual standard error: 102.2 on 12 degrees of freedom
Multiple R-squared: 0.9519, Adjusted R-squared: 0.9479
F-statistic: 237.6 on 1 and 12 DF, p-value: 2.846e-09
