With measurement errors taken into account in the simultaneous fitting of the measurement and the new regression equations, estimation of is unbiased; hence it reflects the true relationship much better. Certainly, introducing latent factors in models is not a free lunch..
A function point is a unit of measurement to express the amount of business functionality an information system (as a product) provides to a user. Function points measure software size. The cost (in dollars or hours) of a single unit is calculated from past projects. As of 2013, there are several recognized standards and/or public specifications for sizing software based on Function Point. 1. ISO Standards. 1  COSMIC: ISO/IEC 19761:2011 Software engineering.
Functional fixedness is a cognitive bias that limits a person to using an object only in the way it is traditionally used.The concept of functional fixedness originated in Gestalt Psychology, a movement in psychology that emphasizes holistic processing.herefore, there is a need to overcome the prototype in order to avoid functional fixedness.
