Results of SPSS binary logistic regression dependent variable is Awareness of agricultural insurance and found significant variable education at 5% level and odd ratio is 56 .What does it mean?
LOGISTIC REGRESSION
The model here is parametric in a form of: p = 1 / (1 + B-y)
where Y = b0 + b1x1 + b2x2
ODD RATIO
This is non-parametric, i.e. the ratio of the odds A in the presence B or A without B. It is not a test for the relationship between A and B, but the probability of A with B and A without B. In he 2x2 table, the odds ratio is: ad / bc
INTERPRETATION
The two results: (i) significance test of logistic regression, and (ii) odd ratio test , are two different things: (i) is parametric test, and (ii) is non-parametric test. In case where the independent variable is continuous, the equivalence for purpose of comparison of the odd ratio is: OR = exp(b1)
In you SPSS print out, you have the logistic function, take b1 of that function and take its exponent id your independent variable is continuous.
