What does {zscorer} do?

The {zscorer} packages facilitates the calculation of a range of anthropometric z-scores (i.e. the number of standard deviations from the mean) and adds them to survey data:

  • Weight-for-length (wfl) z-scores for children with lengths between 45 and 110 cm

  • Weight-for-height (wfh) z-scores for children with heights between 65 and 120 cm

  • Length-for-age (lfa) z-scores for children aged less than 24 months

  • Height-for-age (hfa) z-scores for children aged between 24 and 228 months

  • Weight-for-age (wfa) z-scores for children aged between zero and 120 months

  • Body mass index-for-age (bfa) z-scores for children aged between zero and 228 months

  • MUAC-for-age (mfa) z-scores for children aged between 3 and 228 months

  • Triceps skinfold-for-age (tsa) z-scores for children aged between 3 and 60 months

  • Sub-scapular skinfold-for-age (ssa) z-scores for children aged between 3 and 60 months

  • Head circumference-for-age (hca) z-scores for children aged between zero and 60 months
