Perhaps you should try some spelling variations:
"estimating functions using computation code" » "estimating equations using computation code" (Expand search), "generating functions using computation code" (Expand search), "estimating equation using computation code" (Expand search), "estimating functions using computational code" (Expand search), "estimating functions using imputation code" (Expand search), "estimating functions using compilation code" (Expand search), "estimating functions using computation model" (Expand search), "estimating functions using computation co" (Expand search), "estimating function using computation code" (Expand search), "estimating reactions using computation code" (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: "((\"estimating functions using computation code\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( estimating functions using computation code ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("estimating functions using computation code") OR ("using coding python python programming"))*.
