Find the mathematical link between two variables and a measured quantity.
This technical note presents a Fortran program that builds empirical expressions for data collected at combinations of two variables. It explains how to organize data, run the computations, and interpret the results.
The book walks you through practical data layouts, including cases with a single value per cell and with replicates. It also covers options to modify data, interpret output, and understand the role of variance, significance tests, and residuals in the analysis. With tables, appendices, and step-by-step instructions, you can apply the procedure to your own experiments.
- How to prepare data for computer input and what the program can compute
- Different modeling approaches, including linear and quadratic models
- How to modify data, omit or transform observations, and generate diagnostics
- How to read the computer output, including variance components and significance tests
Ideal for researchers and practitioners who need a structured, repeatable way to fit empirical expressions to two-variable data and to assess the reliability of the results.
