The enclosed file Traces.csv, contains the service time of requests given to 4 different web services, one for each column.
For each column:
• Fit the data against the uniform, the exponential, the two stages hyper-exponential and the two stage hypo-exponential distributions using the method of moments
• Fit the data against the exponential, the two stages hyper-exponential and the two stage hypo-exponential distributions using the method of maximum likelihood
• With a plot, graphically compare the CDF of the considered distributions, using the parameters obtained by both fitting procedures. In the plot, also include the approximated CDF obtained directly from the dataset.
