How do you compare proc?

How do you compare proc?

COMPARE=SAS-data-set specifies the data set to use as the comparison data set. If you omit COMPARE=, then the comparison data set is the same as the base data set, and PROC COMPARE compares variables within the data set. If you omit COMPARE=, then you must use the WITH and VAR statements.

How do I compare two sets of data in SAS?

Here’s how to check if two datasets in SAS are the same:

  1. Start the comparison procedure with the PROC COMPARE statement.
  2. Use the BASE=-option to specify the name of the first dataset.
  3. Use the COMPARE=-option to specify the name of the second dataset.
  4. Finish and execute the procedure with the RUN statement.

How do you compare two observations in SAS?

Program Description

  1. Declare the PROCLIB SAS library.
  2. Set the SAS system options.
  3. Sort the data sets by the ID variable.
  4. Specify the data sets to compare.
  5. Create the Result output data set and include all unequal observations and their differences.
  6. Specify the ID variable.

How do I compare two SAS codes?

How to compare SAS programs in SAS Enterprise Guide

  1. Install a file comparison tool. I like WinMerge.
  2. Set your File Comparison options in SAS Enterprise Guide. Select Tools->Options, then the File Comparison tab.
  3. Select the two files that you want to compare.

How does proc compare work in SAS?

The COMPARE procedure compares the contents of two SAS data sets, selected variables in different data sets, or variables within the same data set. PROC COMPARE compares two data sets: the base data set and the comparison data set. The procedure determines matching variables and matching observations.

Does Proc compare need to be sorted?

You can specify more than one variable, but the data set must be sorted by the variable or variables that you specify.

How do I compare two datasets?

When you compare two or more data sets, focus on four features:

  1. Center. Graphically, the center of a distribution is the point where about half of the observations are on either side.
  2. Spread. The spread of a distribution refers to the variability of the data.
  3. Shape.
  4. Unusual features.

What is Proc compare in SAS?

How do you match data in SAS?

To match-merge, you simply specify the data sets you would like to merge in a MERGE statement, and indicate the variables on which you would like to merge in a BY statement. One thing to keep in mind, though, is you can’t match-merge SAS data sets unless they are sorted by the variables appearing in the BY statement.

How do you compare values in two different DataFrames?

Steps to Compare Values Between two Pandas DataFrames

  1. Step 1: Prepare the datasets to be compared. To start, let’s say that you have the following two datasets that you want to compare:
  2. Step 2: Create the two DataFrames.
  3. Step 3: Compare the values between the two Pandas DataFrames.

How do you compare ranked data?

For your first question, convert your choices into numerical data(in order) for each group and then take the absolute difference between each choice from each person in each group. The ones that have the biggest difference could possibly be considered the ones that each group perceives the most different.

What is the difference between compare= and Proc compare?

If you omit COMPARE=, then the comparison data set is the same as the base data set, and PROC COMPARE compares variables within the data set. If you omit COMPARE=, then you must use the WITH statement.

What is the outstats= data set in Proc compare?

The OUTSTATS= data set contains an observation for each summary statistic for each pair of variables. The data set also contains the BY variables used in the comparison and several variables created by PROC COMPARE: _VAR_

When to use proc compare vs listall?

PROC COMPARE prints 0 for any summary statistic that is less than number. A report that contains many trivial differences is easier to read in this form. lists all variables and observations that are found in only one data set. using LISTALL is equivalent to using the following four options: LISTBASEOBS, LISTCOMPOBS, LISTBASEVAR, and LISTCOMPVAR.

What are the values in this observation in Proc compare?

The values in this observation are the differences between the values in the base and comparison data sets. For character variables, PROC COMPARE uses a period (.) to represent equal characters and an X to represent unequal characters. PROC COMPARE writes this type of observation to the OUT= data set by default.
