Re: Insert data from a bigger dataset into a smaller dataset

Hi,    Yes, I produced B from A using a matching code, matching cases and controls. However, Dataset A got the values (no/yes) of 4 numeric variables changed. That means that 4 columns received new values in dataset A.    I need to implement these changes that were made in Dataset A into Dataset B. I cannot simply run another matching procedure with Dataset A because I am already using the results of all other variables from Dataset B. And Matching would create another random dataset.     B is just a subset of observations in A.    Thank you,      ... View more

Dear Kurt,    Thank you for your answer.    Sorry but could you please clarify what do you mean by  if _n_=1 ? Also, what is this declare hash (dataset: Also, what is this rc=c.find.    Finally, the datasets are indeed sorted by ID numbers. However, they have  different population sizes.    I am sorry for my ignorance...     ... View more

I have a bigger dataset (Dataset A) that I used to generate a smaller dataset (Dataset B).    It turns out that 4 numeric variables from Dataset A were updated (Dataset C). Now I need to update these variables in dataset B too. Dataset A and B have in common ID numbers.    Can you please help me find a code to run this update?   You can name:   Dataset A: datasetA Dataset C: datasetC ID numbers: IDnum Variables that need to be updated: Var1 Var 2 Var 3 Var4   Thank you,    Jose Diego.          ...

Hi,    I am doing the Data Setup of the course entitled:  Statistics 1: Introduction to ANOVA, Regression, and Logistic Regression.   I am following the Setup instructions for SAS University Edition: SAS Studio.    However, I am unable to navigate and expand ECST142.    I have downloaded the ZIP file and extracted the files as required. Please see the pictures below.  When I click run I am getting the error as shown in the second picture below.    I have also attached a screenshot of the error for better visualization.    Thank you,    firesantos.  ...
