Abstract
A computing device updates date values in a read dataset to support data analytics. Outlier and non-outlier date values are identified by, for each date value as a respective date value, reading a predefined number of neighboring date values relative to the respective date value; computing a median value and a median absolute deviation value of the predefined number of neighboring date values; computing a difference between the respective date value and the median value; dividing an absolute value of the difference by the median absolute deviation value to define a deviation value; comparing the deviation value to a threshold deviation value; and, based on the comparison, identifying the respective date value as an outlier or a non-outlier date value. Each identified non-outlier date value is updated with a new date computed using a date offset value. Each updated, identified non-outlier date value is replaced in a date updated dataset.
