Multiple text comparisons (for experienced users)

When a search list has been developed which it is considered can be applied reliably to a series of comparable texts, this procedure allows their direct comparison simply by selecting the file names and specifying the context unit and other optional settings to be applied. With a bit of experience, this allows you to speed up the process of comparing larger numbers of texts, without the need to examine each one individually in detail.   

As with the  HAMLET Joint Frequencies routine, statistics are first generated for individual and joint frequencies of items in the search list , expressed in the specified unit of context, for each of the texts selected.  You will be prompted to supply these details when selecting one of the analytical options:

 Procrustean Individual Differences Scaling (PINDIS) can be applied to the series of configurations obtained by multidimensional scaling of the matrices of joint frequencies generated for each text, Individual Differences Scaling (INDSCAL)  applied directly to the collection of matrices.  The MINISSA scaling of the matrix for the first text entered above is automatically used as the starting configuration for this version of INDSCAL, so that the stability of the results can be checked by varying the order in which texts are entered.
