There are a lot of techniques and methods for prediction of bankruptcy among them “Statistical methods” or econometrics techniques are more popular. As dependent variable in our study is qualitative it is convenient to use qualitative discrete models. Mixed Logit model is one of the powerful and flexible techniques of discrete choices that allow the coefficients to be random with distribution f...
this study is aimed at comparison of two quantitative model arima and madm in predicting manpower costs. also qualitative issue and problems of manpower planning are transformed in to qualitative one’s so as optimum planning and forecasting be made. in this study, we first used the time- series models especially arima, to fit forecasting manpower costs in shiraz hafez tile mfg. plant and extrac...
among the most important sources of competitive advantage, is creating and developing strategic alignment competency. strategic alignment, literally, is an abstract and qualitative concept. and a qualitative concept while not been quantified and operationalized, does not worth paying attention practically. this article basing on a general formula and taking systems dynamics approach, suggests a...
Purpose: The purpose of this study was to design a suitable model for the educational system in University of Applied Science and Technology. Methodology: This research was a qualitative-quantitative research. In the qualitative section of the research, the main components of the model for the educational system of this university have been identified by interviewing the experts. In the quantit...
The state estimation of a quantized system (Q.S.) is a challenging problem for designing feedback control and model-based fault diagnosis algorithms. The core of a Q.S. is a continuous variable system whose inputs and outputs are represented by their corresponding quantized values. This paper concerns with state estimation of a Q.S. by a qualitative observer. The presented observer in this pape...
This research aims to identify the facilitating factors of learning transfer in NIGC, using a mixed research method. In the qualitative phase, 16 experts of NIGC and university faculty members were selected as the research sample. In the qualitative phase, survey research method was applied and a sample of 376 subjects was selected based on Cochran formula. In order to analyze the qualitative d...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
Background and Objective: Sulfur mustard (SM) is a chemical warfare agent used by the Iraqi forces during the Iraq-Iran war. So far some statistical methods have only been applied to discriminate between exposed and non-exposed Sardasht inhabitants, using immunological variables. This paper focuses on allocating objects to exposed and non-exposed groups and choosing the best model, using a vari...
