combination of fixed effects, separated by "`+`

" and "`*`

"

- max_interaction_size
maximum interaction size in the formula, up to `3`

- max_effect_frequency
maximum count of an effect in the formula, e.g. the `3`

A's in `"A * B + A * C + A * D"`

- num_effects
number of unique effects included in the formula

- min_num_fixed_effects
minimum number of fixed effects required to use the formula,
i.e. the index in the alphabet of the last of the alphabetically ordered effects (letters) in the formula,
