Attribute |
Public Percentage accuracy |
![]() changed=new definition=The extent to which the value is expected to be free from error, measured as a percentage of the data value. 100% means fully accurate. order=2 origin=DATEX originalCode=ACU originalName=Accuracy type=content |
Public ComputationMethodEnum computationalMethod |
![]() changed=yes definition=Method of computation which has been used to compute this data value. order=3 origin=DATEX originalCode=COM originalName=Computation method type=content |
Public Boolean dataError |
![]() definition=Indication of whether the value is deemed to be erroneous by the supplier, (true = erroneous). If not present the data value is assumed to be ok. This may be used when automatic fault detection information relating to sensors is available. order=0 origin=- null - originalCode=- null - originalName=- null - type=content |
Public NonNegativeInteger numberOfIncompleteInputs |
![]() changed=new definition=The number of inputs detected but not completed during the sampling or measurement period; e.g. vehicles detected entering but not exiting the detection zone. order=4 origin=- null - originalCode=- null - originalName=- null - type=content |
Public NonNegativeInteger numberOfInputValuesUsed |
![]() changed=new definition=The number of input values used in the sampling or measurment period to determine the data value. order=5 origin=- null - originalCode=- null - originalName=- null - type=content |
Public MultilingualString reasonForDataError |
![]() definition=The reason why the value is deemed to be erroneous by the supplier. order=1 origin=- null - originalCode=- null - originalName=- null - type=content |
Public Float smoothingFactor |
![]() changed=new definition=Coefficient required when a moving average is computed to give specific weights to the former average and the new data. A typical formula is, F being the smoothing factor: New average = (old average) F + (new data) (1 - F). order=6 origin=DATEX originalCode=SMF originalName=Smoothing factor type=content |
Public Float standardDeviation |
![]() changed=new definition=The standard deviation of the sample of input values from which this value was derived, measured in the units of the data value. order=7 origin=- null - originalCode=- null - originalName=- null - type=content |
Public Percentage supplierCalculatedDataQuality |
![]() changed=new definition=A measure of data quality assigned to the value by the supplier. 100% equates to ideal/perfect quality. The method of calculation is supplier specific and needs to be agreed between supplier and client. order=8 origin=- null - originalCode=- null - originalName=- null - type=content |
