This free online software (calculator) computes Path Models with Latent Variables by the Partial Least Squares Approach. There is a maximum of 8 latent variables that can be defined. The relationship between the latent variables is defined through a lower triangular matrix (column variables have an impact on row variables). Load the default data set to see a working example of the PLSPM.
Enter (or paste) a matrix (table) containing all data (time) series. Every column represents a different variable and must be delimited by a space or Tab. Every row represents a period in time (or category) and must be delimited by hard returns. The easiest way to enter data is to copy and paste a block of spreadsheet cells. Please, do not use commas or spaces to seperate groups of digits!
