SmartPLS
SmartPLS is a software with graphical user interface for variance-based structural equation modeling (SEM) using the partial least squares (PLS) method. The software can be used in empirical research to analyse collected data (e.g. from surveys) and test hypothesized relationships. Since it is programmed in Java, it can be executed and run on Windows and Mac OS operating systems.
==Data==
SmartPLS uses raw data. The data import uses the text (.txt) and comma separated values (.csv) file format. The columns of the data file represent the variables; the rows represent observations and responses. Only the first row of the data matrix, which becomes the header in SmartPLS, can contain text. Otherwise, only numbers are allowed. Empty cells (e.g., if a missing value occurs) are not allowed. A number that is not used otherwise in the dataset (e.g., -999,999) must be used to fill empty cells. After data import, the user can indicate that this number represents a missing value. SmartPLS automatically identifies the data and number format (e.g., Europe or USA). If a problem occurs, the user can later determine file format specifications and the number format in the software. In addition to the variables used as indicators for PLS path modeling, the data matrix can contain a weighting vector of the observations and responses (e.g., for carrying out weighted PLS path modeling analyses) and grouping variables (e.g., for conducting a PLS multigroup analysis, PLS-MGA).
