The use of discriminatory analysis to determine the factors and variables affecting the efficiency of markets in the city of Erbil

Abstract

Markets are among the important urban areas at the city level and represent specialized
areas for the exchange of goods and services between the seller and the buyer, especially
those that are located in the centers of historical cities, where the areas attract traffic
people and cars. It interferes with other service and religious uses and is located on its
edges residential areas. These factors and influences were distributed at several levels of
planning, design, environmental and social, which together affect the performance of the
markets.
The research found that differential functions have the ability to distinguish (separate)
between these groups, and the first function has a high distinction force between variables
compared to the second function. The results also proved that the classification according
to the formula of the linear discrimination function gives the least probability of a
classification error by applying it to data pertaining to the three groups of markets.
