Hi Namrata
The term "threshold value" has a wide applicability and meaning in data
calculation and generating various
reports in DHIS 2 application, although it is more general concepts of Science.
For example,
1. In computer science: A point beyond which there is a change in the manner a
program executes; in particular, an error rate above which the operating system
shuts down the computer system on the assumption that a hardware failure has
occurred.
2. In control systems: The minimum input that produces a corrective action in
an automatic control system.
3. In Electro-Maganatic Weave (EMW): The minimum intensity or value of a
signal, etc., that will produce a response or specified effect represents a
frequency threshold.
In data collection and analysis tool like DHIS2, one can determine threshold
value for so many available
domain model constraints including data element value, indicator value, data
entry statistic, validation result statistic etc. For example
a.) In data entry module: The mini-max value of specific data elements
represents threshold value for that data element. For example, if a data
element has min value 6 and max is 28, than 6 represents threshold value for
that data element in specific data entry form or data entry screen.
b.) In data quality module: The specific value to pass a specific validation
rule represents threshold value
for that validation rule. For example, total birth should not be less than live
birth plus still birth, than
in this context live birth plus still birth is the threshold value for total
birth in that validation rule.
c.) In data entry form or in data set module: The minimum number of data
elements to be filled to pass data
completeness for a specific data set represents threshold value for that data
set. For example, in a data set, there are 16 data elements, but to pass data
completeness, one need to enter data element value for at least 6 out of 16
data elements, than the total number of data elements = 6, represents threshold
value for that specific data set.
d.) In data element and indicator module: The target value defined for specific
indicator for a specific
period, represents threshold value for that indicator. For example, if target
is predefined for all PHCs in a state in terms of total institutional delivery
in a month should not be less than 60, than total number of institutional
delivery should not be less than 60 in a month for a PHC to pass the target for
institutional delivery for any PHC belongs to that state represents the
threshold value for that target. Thus, in this case 60 is the threshold value
for this specific target.
e.) In report module: The total number of input parameters required to be
entered to generate a report is the threshold value for that report. For
example, to generate a monthly MIS report for a PHC, user need to enter
or select four input parameters ie. period type, period, name of organization
unit, and name of that report,
than the total number of input parameters is 4 and this is the threshold value
for that report. etc
I am not sure about is there any specific WEB API call in DHIS2 for this purpos
but sure the average value for any indicator or data element for specific time
period interval does not represents threshold value for that data element or
indicator.

Hi,
I want to calculate threshold value for data element or indicators i.e.(Average
of three previous years * 1.5) in the app. Is there any WEB API call to get
threshold value or I need to calculate in app?
Thank you
