Dear all,

in principal I want to carry out a chi-square goodness of fit test (csgof or chitest).

However my dataset is a bit unusual. It comes from a questionaire, where participants had to state probabilities for 10 possible outcomes. That is I do not have one variable with categories of observations, where a goodness of fit test would be applicable, but ten variables each containing a probability.

Actually I'm only interested if the mean of these peobabilities over participants is different from hyposized proportions. If I use a simple ttest I can only test each of the variables one by one. But I want to test the distribution over the ten.

Any ideas?

Christoph
