请问R中lda函数的几个输出代表什么意思,我的输入和输出如下:
> j<-read.table("d:\\a.txt")
> j
V1 V2 V3
1 1 2 3
2 11 15 16
3 14 16 19
4 3 5 7
5 16 17 19
6 5 6 5
7 25 23 29
> f<-scan("d:\\d.txt")
Read 7 items
> f
[1] 0 1 1 0 1 0 2
> lda(j,f)
Call:
lda(j, f)
Prior probabilities of groups:
0 1 2
0.4285714 0.4285714 0.1428571
Group means:
V1 V2 V3
0 3.00000 4.333333 5
1 13.66667 16.000000 18
2 25.00000 23.000000 29
Coefficients of linear discriminants:
LD1 LD2
V1 -0.2528760 0.7852387
V2 0.5273609 -1.1972942
V3 0.3697051 0.2932140
Proportion of trace:
LD1 LD2
0.9362 0.0638

请问Coefficients of linear discriminants和Proportion of trace表示什么意思?
谢谢
