Perhaps you should try some spelling variations:
"statistical analyses" » "statistische analyse"
"statistics analysis" » "static analysis", "plastics analysis", "statistische analyse"
"statistical annex" » "statistical appendix"

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: (("statistical analysis") OR ((("statistics analysis") OR ((("statistical analyses") OR ("statistical annex")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"statistical analysis\") or (((\"statistics analysis\") or (((\"statistical analyses\") OR (\"statistical annex\"))))))".
• Removing quotes may allow a broader search: (( statistical analysis ) or ((( statistics analysis ) or ((( statistical analyses ) OR ( statistical annex )))))).
• Adding a wildcard symbol may retrieve word variants: (("statistical analysis") or ((("statistics analysis") or ((("statistical analyses") OR ("statistical annex"))))))*.
