PPFM Tutorial - Garcia-Neto, Manoel; Kebreab, Ermias (My University, 2020)
The Practical Program for Forces Modeling (PPFM) is a spreadsheet for adjusting growth curves with subsequent evaluation and analysis of acting forces. https://sites.google.com/view/ppfm-spreadsheet/ The spreadsheet is use-friendly, with point-and-click tools, being in the public domain. The PPFM spreadsheet features a completely new approach to growth assessment, with great flexibility and practicality of adjustments, allowing visual and numerical comparison without the need to type command lines, being user-friendly with point-and-click tools based on Excel 2010 or higher.
