Multilevel Models

کاربردی از مدل های رگرسیون لجستیک ترتیبی دوسطحی در تعیین عوامل موثر بر بار اقتصادی بیماری دیابت نوع دو در ایران

In recent years, multilevel regression models were intensely developed in many fields like medicine, psychology economic and the others. Such models are applicable for hierarchical data that micro levels are nested in macros. For modeling these data, when response is not normality distributed, we use generalized multilevel regression models. In this paper, at first, multilevel ordinal logist...

CAMAC: a context-aware mandatory access control model

Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...

A Computationally Efficient State Space Approach to Estimating Multilevel Regression Models and Multilevel Confirmatory Factor Models.

Although the state space approach for estimating multilevel regression models has been well established for decades in the time series literature, it does not receive much attention from educational and psychological researchers. In this article, we (a) introduce the state space approach for estimating multilevel regression models and (b) extend the state space approach for estimating multileve...

طراحی مدل تحلیل پوششی داده‌های چند سطحی در ارزیابی کارایی موسسات مالی

Nowadays, one of the key issues in many organizations, especially in institutions such as banks with many branches, is that is the method for evaluating their performance is not a rational and correct method. Conventional techniques, used to evaluate performance, are single-level and cannot provide enough managerial information to identify the inefficient factors of the inefficient units and at...

Testing Multilevel Mediation Using Hierarchical Linear Models Problems and Solutions

Testing multilevel mediation using hierarchical linear modeling (HLM) has gained tremendous popularity in recent years. However, potential confounding in multilevel mediation effect estimates can arise in these models when within-group effects differ from between-group effects. This study summarizes three types of HLM-based multilevel mediation models, and then explains that in two types of the...
