In statistics , pathanalysis is used to describe the directed dependencies among a set of variables. This includes models equivalent to any form of multiple regression analysis , factor analysis, canonical correlation analysis, discriminant analysis, as well as more general families of models in the multivariate analysis of variance and covariance analyses MANOVA, ANOVA, ANCOVA .

Orphan date February 2009 unreferenced date March 2008 Pathanalysis , in Internet website analytics , is a process of determining a sequence of pages visited in a visitor session prior to some desired event, such as the visitor purchasing an item or requesting a newsletter. The precise order of pages visited may or may not be important and may or may not be specified. In practice, this analysis is done in aggregate, ranking the paths sequences of pages visited prior to the desired event, by descending frequency of use. The idea is to determine what features of the website encourage the desired result. Fallout analysis, a subset of pathanalysis, looks at black holes on the site, or paths that lead to a dead end most frequently, paths or features that confuse or lose potential customers.

In statistics , scale analysis is a set of methods to analyse survey data, in which responses to questions are combined to measure a latent variable . These items can be dichotomous e.g. yes no, agree disagree, correct incorrect or polytomous e.g. disagree strongly disagree neutral agree agree strongly . Any measurement for such data is required to be reliable, valid, and homogeneous with comparable results over different studies. Constructing scales The item total correlation approach is a way of identifying a group of questions whose responses can be combined together into a single measure or scale. This is a simple approach that works by ensuring that, when considered across a whole population, responses to the questions in the group tend to vary together and, in particular, that responses to no individual question are poorly related to an average calculated from the others. Measurement models Measurement is the assignment of numbers to subjects in such a way that the relations between the objects are represented by the relations between the numbers Michell, 1990 .

Plot Luna and Amar are a young Bosniaks Bosnian couple living in Sarajevo. Both have traumatic memories from the Bosnian War of the 1990 s. Luna had seen her parents killed by an anti Muslim militia in Bijeljina , and had come to Sarajevo with her grandparents as a child refugee. Amar had served as a soldier in the war and lost his brother. At present, however, they have apparently built up a successful life she as an air hostess with B&H Airlines , he as an air traffic controller at the Sarajevo International Airport . When she comes back from a flight they make love passionately and go to have a good time at a local nightclub. Though identifying as Islam in Bosnia and Herzegovina Muslim s in the context of Bosnia s ethnic set up, religion plays no part in their life. In fact, Amar drinks alcoholic drinks a bit too much which is forbidden by Islam and it is this which begins to put their relationship under strain. First of all, Amar loses his job for being drunk at work. Luna is very worried and has little hope of realizing her fragile dream of having a child with Amar. But her fears for their future increase when Amar takes on a well paid job in a Muslim community hours away from where they live. Only after quite some time has elapsed during which they have had no contact ... and Amar together on the path to a lifetime of happiness.

Path coefficients are standardized versions of linear regression weights which can be used in examining the possible causal linkage between statistical variable s in the structural equation modeling approach. The standardization involves multiplying the ordinary regression coefficient by the standard deviations of the corresponding explanatory variable these can then be compared to assess the relative effects of the variables within the fitted regression model. The idea of standardization can be extended to apply to partial regression coefficients. The term path coefficient derives from Wright 1921 , where a particular diagram based approach was used to consider the relations between variables in a multivariate system. ref Dodge, Y. 2003 The Oxford Dictionary of Statistical Terms , OUP.
