I have a set of data points (1, 3, 5, 7, 9 and 43.7, 24.9, 15, 10.6, 5).
I write it with a heading in "Regneark" (spreadsheet), select the relevant data and choose "Regressionsanalyse" (regression analysis). I get a box named "Data kilde" (data source), but when pressing "Analyser" (analyse) nothing happens. Usually a regression tool emerges.
I then try to plot my data creating a liste of datapoints and using the input line "FitExp[liste1]" or "FitVækst[liste1]" where liste1 is the default name of my dataliste. The result is the box "GeoGebra - Fejl" (error) with the text "Trist, men dette input kan ikke bruges".
What is wrong?
The same question 
I've got the same problem at the moment.
Problem seems to be solved. I downloaded and installed the newest version of GeoGebra.
This problem happens because regression analysis needs LaTeX and it's sometimes not initialized properly. Please wait for 5.0.289.0 or create an object to initialize LaTeX first:

Sorry about that, please try 5.0.289.0 (now online)
