Background and Objective: Discriminant analysis and logistic regression are classical methods for classifying data in several studies. However, these models do not lead in valid results due to not meeting all necessary assumptions. The purpose of this study was to classify the number of Children Ever Born (CEB) using decision tree model in order to present an efficient method to classify demogr...
car-following models are among the most important components of micro traffic flow simulation which is studiedby transportation experts to evaluate new applications of intelligent transportation systems. until now, several carfollowingmodels have been proposed. an obvious disadvantage of the former models is the great number of parameterswhich are difficult to calibrate. in this paper, a car-fo...
Background & objective: One of the common purposes of medical research is Determination of effective factors on the occurrence of event. Due to the interaction of risk factors regression models, discriminant analysis and classification procedures used. Uses of these models require making the assumption which in the medical data isn’t usually established. Therefore, alternative methods must be u...
The relationship between the incidence of bacillary dysentery and meteorological factors was investigated. Data on bacillary dysentery incidence in Shenyang from 1990 to 1996 were obtained from Liaoning Provincial Center for Disease Control and Prevention, and meteorological data such as atmospheric pressure, air temperature, precipitation, evaporation, wind speed, and the amount of solar radia...
Triticale is a promising food crop that combines the yield potential and grain quality of wheat with disease environmental tolerance rye. The objective this study was to evaluate impact genotype, environment management on spring winter triticale variability, using data from 31 locations across whole Poland, 2009 2017, Classification Regression Tree (CART) analysis. It found CART able detect dif...
Background and Objective: Unwanted pregnancy is a pregnancy that is considered to be unwanted by at least one member of the couple, and has adverse consequences for the family and community. Using four classification models, this study predicted unwanted pregnancy in the urban population of Khorramabad and compared these classification models. Materials and methods: In this cross-sectional s...
vehicle occupants comprise a considerable proportion of traffic crash victims in iran. this paper has focused on vehicleoccupants’ injury severity and employed the classification and regression tree (cart) technique in order toidentify the most important variables affecting the injury severity of these road users in crashes occurred on rural freewaysand multilane highways in iran over a three y...
