The use of jackknife confidence intervals with the Richards Curve for describing avian growth patterns by David W. Bradley, Ross E. Landry, and Charles T. Collins. Bull. Southern California Acad. Sci., 83(3):133-147, 1984. A method is presented for measuring growth patterns in birds in which the Richards curve is used as a smoothing device for extracting convenient summary statistics from raw growth data. Jackknife confidence intervals for these statistics are developed and evaluated with Monte Carlo simulation. Strategies for making interspecific and intraspecific comparisons among populations are discussed for both longitudinal and cross-sectional sampling schemes with emphasis on the appropriate scope of inference from different levels of sampling.
