Help: relationship between Regime type and war

#1
Hy guys,

i have a question and it's really important. I have to study the relationship between regime type and intrastate war. the dataset from regime type ranges from 10 (full democracy) to -10 (full dictatorship). the dataset of intrastate war is from the CoW and it s coded 1 for war and 0 for peace. How can i calculate the relationship from the dataset below? how can i do this on spss? Thank you, tom.

here's my dataset ( all between 1800 and 2007):
regime type -10: 32 waryears and 1276 peaceyears
regime type -9: 35 waryears vs. 1086 peaceyears
regime type -8: 29 vs 451
regime type -7: 105 vs 1702
regime type -6: 66 vs 1140
regime type -5: 57 vs 503
regime type -4: 5 vs 614
regime type -3: 49 vs 1019
regime type -2: 4 vs 238
regime type -1: 33 vs 449
