Zipfer is designed to retrieve data from any text file, count the words and createsa proper data file. From the resulting data file, Zipfer can calculate a number of statistics, such as a linear regression equation expressing the relationship between rank and frequency of each different word.
Besides single words, one may now also analyse sentences, paragraphs and word groups.
Additionally, Zipfer creates graphs, showing the zipf curve and errors estimated from the theoretical and actual frequencies.
Zipfer also allows you to export the data for further exploration in more advanced tools such as Excel and SPSS. These files can also be opened by Zipfer again. It is also possible to export the graphs as JPEG pictures, for use in your papers and in websites.
