Formatting probability data to produce confusion matrix for binary data for logistric regression
Hello R folks,
I’m looking to produce a confusion matrix using the command: cmx(PData,threshold=0.49,na.rm=FALSE) for a logistic regression model (1 is habitat, 0 is nonhabitat).
To compile my PData data file (csv file) (as in the example above), I’m using the output of the predict(glm) function. Is there a way to export the output of the predict function (which formats itself as shown below)

logistric regression: model revision
Hello,
I am working on fitting a logistic regression model to my dataset. I removed the squared term in the second version of the model, but my model output is exactly the same.
Model version 1: GRP_GLM<-glm(HB_NHB~elev+costdis1^2,data=glm_1,family=binomial(link=logit))
summary(GRP_GLM)
Model version 2: QM_1<-glm(HB_NHB~elev+costdis1,data=glm_2,family=binomial(link=logit))
