ROC Curve ODS Editing Template Output Problem Step

[sharpmelk]

I am trying to create one images that shows the ROC curves for four factors ( JIF16 JIF5 SNIP SJR). I wanted to change the appearance for journal submission -- largely changing the font (sans-serif), no gridlines, removing top and right borders (if possible, optional), and ensuring a good dpi (they request 1200 but I can't seem to get that high without the java engine error). The code below is what I'm working with (largely from here: http://support.sas.com/resources/papers/proceedings10/233-2010.pdf) . The final image will not be output and I get this error: 

WARNING: The seriesplot statement named 'Step' will not be drawn because one or more of the required arguments were not supplied.

WARNING: The seriesplot statement will not be drawn because one or more of the required arguments were not supplied.

WARNING: The scatterplot statement will not be drawn because one or more of the required arguments were not supplied.

WARNING: A blank graph is produced. For possible causes, see the graphics template language documentation.

What am I doing wrong??

One thing that jumps out at me is that the ";" after "listing" is incorrect. The options after listing are part of the statement. DId you get a syntax error?

[sharpmelk]

Sorry, not sure how that ; got in there. There's no ; after listing in my code. I don't get any errors except for the final seriesplot "step" error.

Without seeing the data, it appears to me that your "subset" data does not contain all of the variables needed by the template. I would suggest doing a PROC CONTENTS on that data set and crosschecking the variable list against your template.

[sharpmelk]

The subset dataset has the outcome STROBE_act_none variable and the 4 predictor variables JIF16, JIF5, SNIP, and SJR although there are some missing values so 50 observations are dropped (because of the nofit option). Is there somewhere in the template text where I am supposed to replace text with these variable names? It generates the output dataset with the calculated sensitivity/1- specificity required for the ROC curve. The code below runs by itself, no problem. It's just the formatting stuff that's the issue. 

ods graphics on; 
proc logistic data=subset plots=roc(id=prob);
model STROBE_act_none(event='0') = JIF16 JIF5 SNIP SJR /nofit; 
roc '2016 Journal Impact Factor' JIF16;
roc '5 Year Journal Impact Factor' JIF5;
roc 'Source Normalized Impact per Paper' SNIP;
roc 'SCImage Journal Rank' SJR;

I think your intent was to use either the ROCOverlayData or the myROCData data sets on the PROC SGRENDER call instead of "subset". The variables in the "subset" data set do not match the ones in the template. The ODS OUTPUT statement below captures the data used for the ROCOverlay and ROC output objects from PROC LOGISTIC. My guess is that you want to render those results in a graph template.

ods output
ROCOverlay=ROCOverlaydata ROC = myROCdata;

[sharpmelk]

I'm working off the documentation in the main thread and I really don't understand what I should be changing. Sorry. I need to use the subset dataset only. 

ods output
ROCOverlay=subset?? ROC = subset;

[DanH_sas]

Change the names of the output datasets to what you had before, then run PROC CONTENTS on them to see which one has the variables you need, Use that data set on the PROC SGRENDER call. You probably shouldn't use "subset" on PROC SGRENDER because that was your input dataset that you had PROC LOGISTIC analyze. I think you're insterested in the plot data from PROC LOGISTIC, which the ODS OUTPUT statement is giving you.
