I am new to SAS and i dont know how to perfom the extraction.</P> Mon, 26 Apr 2021 11:24:51 GMT Landela 2021-04-26T11:24:51Z Missing values.

As in which specific variables by name? Please do not make us guess what is important or what any of the measures mean/do.</P> <P>&nbsp;</P> <P>Every single one of your records has at least one missing value.</P> <P>It also appears that none of your records with the possible explanatory variables appear on a record with the circumference variable. Which is going to make any analysis extremely difficult.</P> <P>&nbsp;</P> <P>&nbsp;</P> Mon, 26 Apr 2021 14:57:26 GMT https://communities.sas.com/t5/New-SAS-User/Missing-values-How-to-extract-the-variables-with-a-specified/m-p/737006#M28778 ballardw 2021-04-26T14:57:26Z
