binomial proportions tests across regions

OZGU GILL
Hi there,

  I have five regions with sample size Region1=13 (Min) to Region5=31 (Max). I have a binomial variable  "none"=0 and "Yes it exists"=1. I have some historical probability for this variable "Yes it exists" test probabilities are for Region1=.20% Region2=.30% etc... I want to test historical prob(test probilities in SPSS) against observed one and for each region at the same time. From GUI I can split the file into regions but I can't assign more than one test prob for each region. Also I want to compare if there is a difference of observed prob for let say Region1 against Region4 to see if there is enough significant difference in proportions. Is there a way to do this on the SPSS GUI interface? Thanks in advance.
