Joao P Dubas	84cf6758bb	fix(growth): results is now a keyword list	2024-10-05 15:10:40 +00:00
Joao P Dubas	7e041ae6c9	chore(growth): adjust indicator lookup to use atoms for unit	2024-10-05 15:09:44 +00:00
Joao P Dubas	82d7009b34	chore(growth): adjust key in ets tables to contain atoms ... The `ets` tables containing growth indicator has a key in the form of `{gender :: atom(), unit :: atom(), value :: number()}`.	2024-10-05 15:07:10 +00:00
Joao P Dubas	fa65a36852	test(growth): fix doctest for centile and percentile	2024-10-05 12:58:36 +00:00
Joao P Dubas	f3846cad24	chore(growth): update doc to reflect percentile values ... This fixes an issue were the returned value represented the measurment at a given z-score (the centile value).	2024-10-03 22:16:15 +00:00
Joao P Dubas	27a7a05584	fix(growth): improve doc for centile calculation ... This module converts a given z-score and Box-Cox values into the related measurement.	2024-10-03 22:14:56 +00:00
Joao P Dubas	5c044e69d9	fix(growth): use centile and percentile correctly ... 1. The calculation made in `Grownth.Calc.Centile.compute/4` converts a given z-score into the expected measurement value. This can be used to get specific values for key z-scores, such as, -3, -2, 2 and 3. 2. To calculate the percentile of a given z-score the system uses the cumulative distribution function.	2024-08-28 13:03:45 +00:00
Joao P Dubas	0d7a4cc9c3	chore(growth): move nil logic to scorer behaviour ... Handle `nil` measurement in `Growth.Score.Scorer`.	2024-06-11 14:53:19 +00:00

Joao P Dubas	fa022b9592	feat(growth): calculate z-score/centile for all indicators ... The `Growth.Score.Scorer` behaviour implements the methods needed to calculate z-score and centile for any indicator.	2024-06-11 11:38:18 +00:00
Joao P Dubas	0ac434c61d	fix(growth): ignore enum result explicitly	2024-06-10 19:24:41 +00:00
Joao P Dubas	06b35cbceb	wip(growth): implement results for bmi ... This implementation should be made generic for all other scores.	2024-06-10 19:09:35 +00:00

Joao P Dubas	4234b2e917	chore(growth): load is independent from task ... Ensure that `Growth.Indicators.Load.all/0` can be run independently from the task. So, the `ets` table is create based on the filename processed.	2024-06-10 13:01:44 +00:00
Joao P Dubas	04fff60541	wip(growth): add score module ... This module is responsible for calculate the z score/centile for each measurement.	2024-06-10 12:15:16 +00:00
Joao P Dubas	b415b38184	feat(growth): load data on application start ... To make this possible, the following changes were made: * Use `Task` to start the load process * Create `ets` table before start the async task * This is needed to keep the tables alive after the task process exits * Adjust the application to start the `Growth.Indicators.Load` task	2024-06-10 12:11:18 +00:00

Joao P Dubas	58f14c0346	wip(growth): fetch|extract|save indicators from WHO ... Initial implementation to fetch growth indicators from WHO. For now, the system merges the measurements for each gender and age group in a single `csv` file. The final solution should do this, saving a `dets` file.	2024-06-04 13:57:32 +00:00
