Whether the value is not applicable, below alevel of quantification or just simply missing, is sometimes not trivial. SAS treats missing values as a very valid value and provides powerful functions that enable great control over their processing.Magnus Mengelbier...

Missing value in a SAS dataset Posted 07-13-2018 10:05 AM (3457 views) Hello, I have found a lot of examples about missing values, either numerical or string but I did not find exactly what I am looking for. I looking for something sample. My dataset could contains a lot of obse...
Accordingly, we also need to introduce the parameter byduprate with the same name and behavior in the %FilterData macro that's invoking the %FilterCols macro. The SAS macro %FilterData also has the same default value 0, but it needs to pass the byduprate argument specified by the user to...
Special Fonts in SAS/QC Software 版本 The CAPABILITY Procedure Missing Values If a variable for which statistics are calculated has a missing value, that value is ignored in the calculation of statistics, and the missing values are tabulated separately. A missing value for one such variable does...

In this example, the series CPI has one embedded missing value, and the series PPI has two embedded missing values. The ranges of the two series are the same as before. Note that the observation for November 1990 has missing values for both CPI and PPI; there are no data for this ...
With the model for X with Zs and Y, we can weigh the two possibilities of the missing value of X, X = 1 and X = 0, in the likelihood function for maximum-likelihood statistical inference on parameters. Since the model for X with Zs and Y contains the parameters of interest, the ...
package on the planet, uses missing value codes almost exactly the same way that Stata uses them. S-Plus uses an internal code (similar to old-style Stata's Good points. I'm not a SAS user, so I'll concede my original complaint. ...
