Perhaps you could share which figures of merit you are looking at and what values they and the Fisher's scores attain?

Marfran C.D. Santos

For example, the plot of the discriminant function DF1xDF2 shows poor class segregation. On the other hand, the sensitivity and specificity values are 100%.

Harold Chike

Marfran, check your input data thoroughly.

Your results appear strange.

Camilo Morais

Marfran, this problem can be related to your code. I've made a Matlab code to solve this issue on Fisher's scores plot. Contact me on private that I'll send the file.

Great Camilo! Thank you.
