Different methods of analytics are popular in various areas of human activities. This also refers to requirements engineering. However, the number of research works on the usage of analytics in requirements engineering is still limited; and the issues addressed in these works are rarely surveyed, structured and organized so that the knowledge of the use of analytics in requirements engineering could be reused and utilized effectively. A preliminary survey of types of analytics used in requirements engineering and a mapping of the types of analytics onto the continuous requirements engineering framework are the steps towards the effective use of analytics in requirements engineering. The survey of the types of analytics provides the linkage to the sources of existing knowledge of the use of analytics in requirements engineering. The mapping of the types of analytics onto the requirements engineering framework points to the sources of data that can be used in different types of analytics in order to enlarge the spectrum of information utilized in requirements identification.
