Knowing consumer attitudes in the field of consumer behavior is a strategic capability. Therefore, the purpose of this study was to investigate the effect of non-traditional promotional tools with guerrilla marketing approach on consumer purchase intention with the mediator variable of customer satisfaction in Hooshmand Khorshid Bahrevar Company in Bushehr Province. For this purpose, a question...

Randomized trials are used to assess the effectiveness of one or more treatments in inducing outcomes of interest. Treatments are typically designed to target key mediating variables that are thought to be causally related to the outcome. Thus, researchers want to know not only if the treatment is effective, but how the mediators affect the outcome. Data from such studies are often analyzed usi...

In randomized trials, researchers are often interested in mediation analysis to understand how a treatment works, in particular how much of a treatment’s effect is mediated by an intermediated variable and how much the treatment directly affects the outcome not through the mediator. The standard regression approach to mediation analysis assumes sequential ignorability of the mediator, that is t...

Swi6 associates with Swi4 to activate HO and many other late G(1)-specific transcripts in budding yeast. Genetic screens for suppressors of SWI6 mutants have been carried out. A total of 112 of these mutants have been identified and most fall into seven complementation groups. Six of these genes have been cloned and identified and they all encode subunits of the mediator complex. These mutants ...

We use causal graphs and a partly hypothetical example from the Physicians' Health Study to explain why a common standard method for quantifying direct effects (i.e. stratifying on the intermediate variable) may be flawed. Estimating direct effects without bias requires that two assumptions hold, namely the absence of unmeasured confounding for (1) exposure and outcome, and (2) the intermediate...

Birnbaum and Mellers criticized the use of partial correlation and multiple regression by Moreland and Zajonc to argue for two independent effects of stimulus exposure on liking. The null hypothesis that one variable mediates the effect of the independent variable on the dependent variables was not tested by their analyses. In response, Moreland and Zajonc reanalyzed their data, using structura...
