Hi All
I came across this paper which does normalization of both rows and columns, and as far as I know we cannot normalize rows and columns simultaneously and also most people prefer to either normalize the row or the column.
But this paper stresses that the data used should be row- and column normalized (so that both rows and columns sum to 0 and have S.D of 1). Normalizing the row first and then performing column normalization on the row normalized data, did not add the rows and columns to zero!
Any idea.. Thanks! :)
I am not sure for the moment, but you are right. So I suppose that the normalization is done on the base of a model which normalize the data at once by row and by column, in order to obtain by row and by column data with S=0 and SD=1.
Still, if you can, please, send me the reference to the article to have a look.
Success,
Alex
that is write what you r saying. but may be they used some software which is using such properties on that basis they write it.
maybe it is definitely a possibility, but when we do row-wise first and then column-wise on the row normalized data, we are able to achieve SD of 1 but the sum is not equal to 0... I am working on it now with the help of my professor.
from my last experience, i did both row and column normalization of my data using some software. that why i told you.
i hope they used only software. why not you can asked to concern author he/ she will gave you a clear cut idea about that.
Yeah I did mail the author, I am yet to get his reply. Could you tell me the software you used for doing it on your data.
