SPSS Statistics

HI. I was using SPSS's multi-layer perceptron, but in the output, I couldnt see anyway to create a confusion matrix and other measures of accuracy.

Can someone show or type how to use the output to compute a confusion matrix. I prefer the matrix to a ROC curve BTW.

Hi @Steve Wong

I searched our online documentation for "confusion matrix" and came back with these two "hits":

• https://www.ibm.com/docs/en/SSLVMB_29.0.0/statistics_mainhelp_ddita/spss/base/idh_disc_cla.html
• https://www.ibm.com/docs/en/SSLVMB_29.0.0/statistics_casestudies_project_ddita/spss/tutorials/plum_germcr_classification.html

Given the definitions here, wouldn't the "Classification results" be the table you are looking for?
