MissingDataMethod
is an option to TemporalData and other functions that controls how to process missing data.
Details
- A missing data method typically provides methods for how to fill in values that are missing.
- Typical settings include:
-
None do no processingAutomatic pick a method automatically"name" use a specified method{"name",opt1->val1,…} use a specified method with particular options
- Possible settings for "name" include "Interpolation" and "Constant".
- The missing data methods for individual functions are documented on the corresponding reference pages.
Examples

Fill in missing data values using linear interpolation:
Use TemporalData to create a complete path:
Fill in missing data values with the mean of available data:
Scope (3)
Use a custom interpolation for filling in missing values:
Fill missing values by keeping the value from the left:
Fill missing values by keeping the value from the right:
Compare the time series:
Fill missing values with an arbitrary constant:
Properties & Relations (4)
The setting Automatic will use the ResamplingMethod setting:
The method for handling missing data does not need to match the ResamplingMethod :
The default missing data method for EventSeries is interpolation of order 0:
The default missing data method for TimeSeries is interpolation of order 1:
The default missing data method for TemporalData is interpolation of order 0:
Possible Issues (1)
The choice of MissingDataMethod will produce varying results:
Do not specify missing values:
Accumulate:
Fill missing values with a constant:
Use interpolation to fill in missing values:
Compare the results:
