In this study, energy security is taken as an ordinal response variable coming from the multinomial distribution with the energy grade levels A, B, C, and D. Thereafter, the world energy security data is tried to be statistically modelled by using generalized linear model (GLM) approach for the ordinal response variable under different cumulative link functions. The cumulative link functions comparatively used in this study are cumulative logit, cumulative probit, cumulative complementary log-log, cumulative Cauchit, and cumulative negative log-log. In order to avoid a multicollinearity problem in the data structure, principal component analysis (PCA) technique is integrated with the GLM approach for the ordinal response variable. In this study, statistically, the importance of determining the best cumulative link function on the accuracy of parameter estimates, confidence intervals, and hypothesis tests in the GLM for the multinomially distributed response variable is highlighted. In terms of energy evaluation, by using cumulative logit as the best cumulative link function, energy sources consumptions, electricity productions from nuclear energy, natural gas, oil, coal, and hydroelectric, energy use per capita and energy imports are found to have statistically significant effects on energy security in the world's energy performance.

Evaluating the Effectiveness of Snyder's Theory-Based Group Hope Therapy to Improve Self-Efficacy of University Students in Finance

“…Hope therapy is a healthcare program based on Snyder's hope therapy designed to enhance hopeful thinking and strengthening activities related to pursuit of goal, which is derived from cognitive-behavioral therapies, solution-based treatments and fictional and narrative treatment (Snyder and Peterson, 2000). In this treatment, participants first get acquainted with the principles of the theory of hope therapy and then they are taught how to apply these principles in their lives (Da Silva Soares et al, 2018;Danby et al, 2018;Eglitis and Popov, 2018;Iyit, 2018;Kmita et al, 2018;Moreno-Fernandez et al, 2018;Taki et al, 2018). Participants learn how to determine important, achievable, and measurable goals, set multiple paths to move toward these goals, identify the motivational resources and interactions of each obstacle to its motivation, review progress towards the goal, and adjust the targets and passages as needed (Ahamed et al, 2017;Khosravi et al, 2018;Martinez Macias et al, 2017;Singh et al, 2018).…”

A Novel Statistical Approach to Investigate Wisconsin Breast Cancer Data by Generalized Linear Mixed Model Approach in Cancer Epidemiology in Medicine

“…The "linear predictor" part and the "link function" of the GLM can be given as follows (Myers et al [59], İyit [60]);…”

“…Generalized linear mixed model (GLMM) approach is an extension of the GLM approach by adding random effect(s) to the "linear predictor" part. A general form of the "link function" of the GLMM as a function of the conditional mean of the response variable given the random effect term () u  can be given as follows (McCulloch and Searle [61], Stroup [62], İyit et al [63]);…”

“…In the GLM and GLMM approaches for the binomially distributed response variable performed in this study, four different binary link functions, namely "logit", "probit", "cloglog", and "cauchit" are used as follows (Morgan and Smith [64], Olsson [65], Koenker and Yoon [66], Hilbe [67], İyit et al [68], İyit and Mashhadani [69]);…”

Gene Cloning and Gene Expression Characteristics of Alcohol Dehydrogenase in Osmanthus fragrans var. semperflorens

“…In the fatty acid derivatives metabolic pathway of apple aroma (Robert, et al, 2007), hexanal transformed by linoleic acid hydroperoxide could generate 2-methylbutanol which can produce 2-isoamyl acetate by the alcohol acyltransferase in presence of ADH (Dudareva et al, 2008). And also, in the mature process of fruits, the expression level of ADH has important influence on the diversity of aroma components, especially the content of aldehydes and alcohols (Iyit, 2018;Jiang et al, 2018;Khan et al, 2018). Studies have indicated that the increase of ethylene content would lead to lower expression of ADH (Defilippi et al, 2005), while the increase of alcohols would make genetically modified fruit more flavor (Speirs J et al, 1998).…”
