R glm summary lists every value of independent variable
I'm running a glm in r on a dataframe with 2 values.
str(INV)
'data.frame': 5614 obs. of 2 variables:
$ MSACode: Factor w/ 70 levels "40","80","440",..: 37 64 58 56 66 14 38 37 66 14 ...
$ NotPaid: Factor w/ 2 levels "0","1": 1 1 1 1 1 1 1 1 1 1 ...
The code I used to run it:
GlmModel <- glm(NotPaid ~ MSACode,family=binomial(link="logit"),data=training)
print(summary(GlmModel))
The result from the summary is showing the individual values rather than just one value for the field.
> print(summary(GlmModel))
Call:
glm(formula = NotPaid ~ MSACode, family = binomial(link = "logit"),
data = training)
Deviance Residuals:
Min 1Q Median 3Q Max
-1.9728 -0.8352 -0.6501 0.9346 2.8245

MSACode1080 1.455e+01 1.697e+03 0.009 0.993
I don't understand these results - why is it showing each MSACode value separately? Thanks.
