This is my first time in a competition. I am wondering what does the classification rate mean?
classification rate = (1/N) * I( y = y_hat )
I don't understand if y is equal to y_hat, then I( y = y_hat ) return 1 or 0. Or it is the other way around? How can I code this into R?
Thank you so much for helping me in advance. This is my first time in a competition, so I hope I did not sound silly for asking a question like this. Thanks!
