The software is available free of charge from Participants need to install the software several days prior to the workshop as it needs to be activated by the SmartPLS administrator. You are encouraged to purchase and bring the Dr. Hair’s book “ A Primer on Partial Least Squares Structural Equation Modeling with you to the workshop (available for about $30 on Amazon ).

Lavaan We are now well into what can be called the "R-age" and it is, well, all the rage alright. R is transforming quantitative analysis. Its role will continue to grow at a dramatic rate for the foreseeable future. There are two R packages dedicated to second-generation SEM analyses ("classical sem", which involved the anaysis of covariance structures). At the moment, I choose the lavaan package to present at this site, which is not to say that the SEM R packages isn’t just fine. http://mypaper.pchome.com.tw/mapckb8g5f61/post/1330379961

It helps us to integrate variables that we propose do exist, but have not been measured (yet). We could for example build a model in which ion flow in certain brain cells is a latent variable and in that way make a prediction about the covariance of the ion flow to observable variables, which, if someone invents a measurement instrument that allows the measurement of this flow in the specific region, can be falsified or confirmed.
