Perhaps you should try some spelling variations:
"statistical inferences" » "statistical inference"
"statistics references" » "statistical inference", "states references"
"statistics inference" » "statistical inference", "statistische inferenz"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("statistics inference") OR ("statistical inferences"))) OR ("statistics references")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"statistics inference\") OR (\"statistical inferences\"))) or (\"statistics references\"))".
• Removing quotes may allow a broader search: (((( statistics inference ) OR ( statistical inferences ))) or ( statistics references )).
• Adding a wildcard symbol may retrieve word variants: (((("statistics inference") OR ("statistical inferences"))) or ("statistics references"))*.
