abstract     in order to study the relationships among seed yield and its components in nigella sativa, path coefficient and factor analysis was done using some agro- morphological traits of 21 different genotypes. genotypes were evaluated using a completely randomized design with four replications in ardestan university research farms. there was a high and positive correlation between seed yie...

The analytic methods often used in drug use studies, such as ANOVA, multiple regression, logistic regression, multilevel models, and structural equation modeling (SEM) including path analysis, factor analysis, and latent growth curve model, are variable-centered approaches. Those approaches assume that the study sample arises from a homogeneous population; and focus on relations among variables...

Extensive research has been focused on the progressive collapse analysis of buildings and most of them are based on the alternative path method (APM) with sudden removal of one or several columns. However, in this method the damage of adjacent elements of removed columns under blast conditions was ignored and this issue can lead to an incorrect prediction of progressive collapse. Therefore, in ...
