INTRODUCTION The analysis of functional magnetic resonance imaging (fMRI) data is a complicated procedure. The large data sets are computationally difficult to manipulate and special modeling techniques are necessary to deal with temporal correlation and to apply results beyond the study population. The statistical models used to analyze fMRI data require numerous steps starting with raw data a...

In the present study, records on 22872 first-parity Holsteins collected from 131 herds by the Animal Breeding and Improvement Center of Iran from 1995 to 2014 were considered to estimate genetic and phenotypic relationships between calving difficulty (CD) and the lactation curve traits, including initial milk yield (Ap), ascending (Bp) and descending (Cp) slope of the lactation curves, peak mil...

menorrhagia is one of the most common gynecological problem and leading causes of poor quality of life and iron deficiency anemia in women of reproductive age. research in gynecological field relies heavily on repeated measure designs. repeated measure studies are helpful in understanding how factors of interest change over time. our goal is to apply statistical methods which are appropriate fo...

purpose: one of the major causes of visual acuity loss in diabetic patients is diabetic macular edema (dme). best-corrected visual acuity and central macular thickness changes are considered as two main outcomes in diabetic macular patients. the goal of this study was to compare the effect of intravitreal bevacizumab injection alone or combined with triamcinolone versus macular photocoagulation...

In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model has been introduced to analyze such observations. A beta distribution represents a flexible density family on (0, 1) interval that covers symm...
