Probabilistic models are commonly used to estimate both the mean value of y and a new individual value for a particular value of x. True or False?

Solution

True. Probabilistic models are commonly used to evaluate quality attributes, such as reliability, availability, safety and performance of software-intensive systems. The accuracy of the evaluation results depends on a number of system properties which have to be estimated, such as environmental factors or system usage.
