Several dates distributions

When a dataset contains several dates (for example birth and death dates), the program can compute the single date distributions and other distributions generated by the relations between the data of each date.
Currently, the program only handles distributions generated by the relations between two dates.

Date differences

Here are examples of distributions built computing the differences between two dates. Distribution: Child, Duration between parents' wedding and birth
Distribution: Father: age at child birth
Distribution: Mother: age at wedding

These distributions are called "age" in the context of this program.

Inter-aspects

"Inter-aspect" is the name used in this program to designate an aspect (an angle) between planets generated by two dates.
For example:
  • The longitude of venus at the moment of father birth is 100°
  • The longitude of mars at the moment of mother birth is 150°
  • Then we say that the inter-aspect between mother's venus and father's mars is 50°
Distribution: Inter-aspects between mother mars and father venus

Hierarchy "distrib2"

As explained in the page about distributions,
  • A distribution representing a single quantity (here distribution by year, by day, and planetary positions) can be represented by an 1-dimensional array (abbreviated dim1).
  • A distribution involving two quantities (here planetary aspects) can be represented either by a 1-dimensional array or by a 2-dimensional array (abbreviated dim2).
The distributions used to describe the relations between two dates are organized in this hierarchy:
distrib2
    ├── age
    │   └── dim1
    │       ├── age-M
    │       └── age-Y
    └── interaspects
        ├── dim1
        │   ├── SO-SO
        │   ├── ...
        │   └── NN-NN
        └── dim2
            ├── SO-MO
            ├── ...
            └── PL-NN
This hierarchy is called distrib2.
