Hello Everyone, I was wondering if there is any tool or formula that allows to generate Z score for stunting using Age, gender, height and weight data, different than the Z score table or the growth charts. Thank you!

There a a number of tools. Functions / libraries exist for STATA.R, and EpiInfo as well as other data analysis systems. The WHO provide a set of free packages for this.

BTW ... I am not sure you can do much with "weight" when calculating height-for-age z-scores.
