December 2009) (Learn how and when to remove this template message) This is the most common of all forms. Instrumental variable analysis requires the measurement of a valid instrumental variable, which is a variable that is independent of the unmeasured confounding and encourages a subject to take one treatment level versus another, while having no effect on the outcome beyond its encouragement of a certain treatment level. In the flame emission spectroscope, the coloured light from a. . domain classes are the analog, digital and time domains. There are many types of literature review and the following types of literature review are the most popular in business studies: Narrative literature review critiques the literature and summarizes the body of a literature.
