get_distinct_state_sequences()

get_distinct_state_sequences() returns the DSS (distinct successive states) representation for each sequence.

Function Usage

from sequenzo import get_distinct_state_sequences
result = get_distinct_state_sequences(seqdata, fill_value=-999)

Entry Parameters

Parameter	Required	Type	Description
seqdata	✓	SequenceData	Input sequence dataset.
fill_value	✗	numeric	Value used for trailing empty DSS slots.

What It Does

• Converts each sequence into distinct successive states (collapsing repeated consecutive states).
• Returns a tabular DSS output for all sequences.

Examples

from sequenzo import get_distinct_state_sequences

dss = get_distinct_state_sequences(seqdata, fill_value=-999)
print(dss.head())

R Counterpart

• Closest TraMineR function: seqdss
• Mapping note: This is a direct conceptual and implementation match in Sequenzo (sequence_statistics.py calls seqdss).

Notes

• Useful when you want spell order without repeated consecutive states.
