Respected Sir Thank You for the ultra fast reply....

Is the work ok???? please confirm .... I am not so much familar with this test... This time it didnt gave any warning message.
Now you fit a different model to your data (just a constant) which does not seem to be very reasonable. You should use a regression model that makes sense for the data - at least within every segment. hth, Z

Overlapping confidence intervals typically indicate that too many breakpoints were selected and/or the model does not fit well. In your case, the BIC selection is probably not the best solution. hth, Z
