i have this error, why?

Undefined function or method 'score' for input arguments of type 'double' please can you help me?

e=res_tst(1,:)-zitr;
t=score(e);

[KSSV]

score accepts data of type table. You are inputting a double...it will throw error. Read more here: https://in.mathworks.com/help/finance/creditscorecard.score.html

The command cannot find the function 'score'. Place the function file in the current working directory or add the file path to the MATLAB 'setpath' for the command to work.

thanks for the answer but how can i get the function file? Can you please send it to me! Thanks

The only Mathworks-provided score() function is an operation specific to creditscorecard objects created by the Finance Toolbox.

The table that KSSV mentions is only for the second input; the first input needs to be a creditscorecard object.

We cannot send you the code for the method; if you do not have the finance toolbox then it is useless to you, and it would violate our license agreements to send it.

Might I suggest that possibly you are looking for zscore() instead of score()? zscore is part of the Statistics and Machine Learning toolbox.

and what about Huber’s score function? hub(e)

[Walter Roberson]

I am not familiar with Huber's score function. Is it related to the 'huber' option of https://www.mathworks.com/help/stats/robustfit.html ?
