《r语言实战》里面回归一章,通过height回归weight,这里有个confint()函数,说提供参数的置信区间,我随便输了几个level,如下,结果看不懂,有大神能解释下吗?多谢
> confint(fit,level=.9)
5 % 95 %
(Intercept) -98.030599 -77.002734
height 3.288603 3.611397
> confint(fit,level=.8)
10 % 90 %
(Intercept) -95.53256 -79.50078
height 3.32695 3.57305
> confint(fit,level=.1)
45 % 55 %
(Intercept) -88.277421 -86.755912
height 3.438322 3.461678
> confint(fit,level=.99)
0.5 % 99.5 %
(Intercept) -105.400380 -69.632954
height 3.175472 3.724528
