A statistical tool that allows us to multiple independent variables are related to a dependent variable is known as multi variable linear regression technique. The examination of these relationships leads to the formation of networks of variables that provide the basis for the dev theories about a phenomenon.

... d provide higher quality and more sustainable construction projects. There are many factors affecting productivity in precast concrete construction sites are availability of experience labour, availability of tools and equipment, frequency of inspection, payment delay, healthy management, health status, quality of framework, maintenance. This study contributes to the construction management knowledge by providing simple but effective models to increase productivity precast elements.
