Given the following conclusions:

(1) In regression analysis, the fit of the model can be judged by the value of the correlation coefficient $R^2$; the larger the $R^2$, the better the fit of the model;

(2) In regression analysis, the fit of the model can be judged by the sum of squares of residuals; the larger the sum of squares of residuals, the better the fit of the model;

(3) In regression analysis, the fit of the model can be judged by the residual plot; if the residuals are evenly scattered around a horizontal band, it indicates that the model is appropriate. The narrower the band, the higher the precision of the fit.

Among these conclusions, fill in the correct ones.
