Updates and modifications:

• Update in %gigs_classify_growth() macro. A BY-group processing logic added to the macro for all outcomes. Parameter BY= added.

• Accepted values of age days accepted for sfga and svn outcomes extended form 0 - 0.5 day to 0 - 3 days. Note: if age days are =>0.5 a warning is issued in the log (SfgaSvnWarn= parameter added to alter that behaviour)

• isBirthMeasurement argument added to the following list of functions:
  gigs_classify_wfa,
  gigs_classify_wasting,
  gigs_classify_stunting,
  gigs_classify_headsize,
  gigs_compute_wfa,
  gigs_compute_wasting,
  gigs_compute_stunting,
  gigs_compute_headsize,
  to allow forcing direct "at birth" calculation (instead evaluation base on age days).

• Documentation updated.

• Notes with examples updated.

Bug Fixes:

Bugs are named after people who reported them. Thank you for your support in makin GIGS better!

• bug reported by Ki-Do - a missing value of p returned from gigs_ig_nbs_value2centile() function was wrongly replaced by 0.9999999999989998.

• bug reported by Emily and Mike - value 1e-323 was not recognized under Linux. 1e-323 was replaced by a call to the constant('small') function to get OS independence.

Overview

Produced as part of the Guidance for International Growth Standards (GIGS) project at the London School of Hygiene & Tropical Medicine, gigs provides a single, simple interface for working with the WHO Child Growth standards and outputs from the INTERGROWTH-21^st project. You will find functions for converting from anthropometric measures (e.g. weight or length) to z-scores and centiles, and the inverse. Also included are functions for classifying newborn and infant growth according to literature-based cut-offs.
