A new model-testing paradigm is introduced. The proposed method uses the structure of the autocorrelation function of the model that we would like to fit the data to. We start by estimating the autocorrelation function of the data, and then apply a curve-fitting criterion, which we call the optimization method. If the resultant error is high, then...

Motivated by the problem of cluster identification, we consider two multivariate normally distributed points. We seek to find the distribution of the squared Euclidean distance between these two point. Con- sequently, we find the corresponding distribution in the general case. We then reduce this distribution for special cases based on the mean and...

Recent studies have shown that malicious packets introduce distribution error and perturb the self-similarity property of network traffic. As a result loss of self-similarity (LoSS) is detected.

We compare the performance o...
