Script File Sections¶
A PoPy script file is hierarchical and based on YAML.
The file is indented with the main sections defined at the start of a line. Subsections are indented within the main sections.
In Table 56 we list the main sections that are common to many Script File Formats.

| MODEL_PARAMS | Define m[X] for each data row, given f[X], r[X] and c[X] |
| STATES | Define initial value s[X], given m[X] and c[X] |
| DERIVATIVES | Define d[X] wrt time, given m[X], c[X] and s[X] |
| PREDICTIONS | Define p[X] for each data row, given m[X], c[X] and s[X] |
