Even though the data step method above works just fine there is a simpler way.

How to change missing values to zero in spss. Many fields in the dataset contain a 999 value indicating a missing value. Recode the data so that the batsmen are rank ordered by their number of runs with the batsman with the highest runs given a code of 1 and the batsman with the lowest runs given a 5. When recoding variables always handle the missing.

On the new window select the tick that says Include if case satisfies condition. Select the estimation method you want to use to replace missing values. Setting Missing Values in SPSS.

Im importing a very large dataset into SPSS. PROC STDIZE lets you easily replace missing values with zero. The data given below represents runs scored by 5 batsmen in a national-level match.

Second missing values may be specified as a range. SPSS Statistics Recode single values in SPSS Statistics. The closest you will come is to change the system-missing value to a user-missing value.

The keyword sysmis can be used on the recode command and it stands for the system-missing value. In the SPSS data view place the cursor on this variable and sort it in ascending order. Furthermore you can easily modify the code to replace missing values for only the desired variables by inserting only those variables into the array.

Furthermore it does so with much less coding than in the data. This can be accomplished with a recode command as is shown below. IF var1 1 var2SYSMIS.

Several methods of coding missing values are reviewed for both numeric and string variables. From Transform Menu -- Recode into Same Variable -- Old and New Variables -- System Missing -- in value space add the value you want to replace the missing data with -- continue -- Ok.

Hi loredana According to the SAS Documentation the MISSING system option does not replace missing values in numeric variables but instead Specifies the character to print for missing numeric valuesso I think that the correct solution for this request would be to use the same approach used to replace the character variables with the coalesce function.

Select the variable s for which you want to replace missing values. Perhaps unsurprisingly missing values can be specified with the MISSING VALUES command. If a range is used a single discrete missing value can be added to it.

A series of lines appear without information. However default each variable in SPSS is set to having no missing values. The correct command syntax is.

A thing to note however is that missing values can be specified for multiple variables at once. Transform Replace Missing Values. Rather than using the recode command use an if statement like this.

This video demonstrates how to code missing values in SPSS. This represents a value instead of a function. Specify the type of value you wish to recode eg a specific value missing data or a range of values and the specific value to be recoded eg a value of 1 or a range of 1-5.

Old and New Values. Once you click Old and New Values a new window where you will specify how to transform the values will appear. In variable view you have to define 999 as being the discrete missing value for each variable.

You can change that by choosing First case in each group is primary And here it says a value of zero in the Primary last variable will mean thats a duplicate and we can delete it Thats fine lets click OK The easiest way to now remove the duplicates s to sort the data by the new variable Primary last.
