Perhaps you should try some spelling variations:
"using computational two sampling errors" » "and computational two sampling errors" (Expand search), "using computational to sampling errors" (Expand search), "using computational tool sampling errors" (Expand search), "using computational tools sampling errors" (Expand search), "using computational two sampling error" (Expand search), "using computational two sampling effort" (Expand search), "using computational two spelling errors" (Expand search), "using computational _ sampling errors" (Expand search), "using computational and sampling errors" (Expand search), "using computational air sampling errors" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking python python programming" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational two sampling errors\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational two sampling errors ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational two sampling errors") OR ("using coding python python programming"))*.
