Use the D-score to analyze and predict early development of children similar to measures like height and weight.\n\nThe `dscore` package contains tools to\n\n-   Map your item names to the GSED convention\n-   Calculate D-score from item level responses\n-   Transform the D-scores into DAZ, age-standardised Z-scores\n\nThe required input consists of *item level* responses on milestones from widely used instruments for measuring child development.\n\n## Installation\n\nYou can install the development version from [GitHub](https://github.com/) with:\n\n``` r\ninstall.packages(\"remotes\")\nremotes::install_github(\"d-score/dscore\")\n```\n\n## Overview\n\nYou may estimate the D-score and the Development-for-Age Z-score (DAZ) from child data on developmental milestones. Four steps are needed:\n\n1.  Identify whether the `dscore` package covers your measurement instrument;\n2.  Map your variable names to the GSED 9-position schema;\n3.  Calculate D-score and DAZ;\n4.  Summarise your results.\n\nThe `dscore` package provides various function that support these steps. See [Getting started](https://d-score.org/dscore/articles/getting_started.html) for more details.\n\n## Resources\n\n### Books and reports\n\n1.
