polkuanalyysit
Polkuanalyysit, often translated as path analysis, is a statistical technique used to estimate causal relationships among a set of variables. It is a special case of structural equation modeling (SEM) where all variables are assumed to be observed, meaning there are no latent variables. The primary goal of path analysis is to examine the direct and indirect effects of independent variables on dependent variables through a hypothesized causal structure represented by a path diagram.
In path analysis, causal relationships are specified as a series of linear equations. The model is built
Key components of path analysis include direct effects, which are the effects of an independent variable on
Path analysis is particularly useful for testing theories about causal processes, understanding how variables influence each
