compute_stage_prob¶

compute_stage_prob(stagetrain, sop, sop_bin_divide)¶

COMPUTE_STAGE_PROB Compute per-bin stage proportions for a feature (e.g., SOpower)

Usage:: [stage_prop, timestamps] = compute_stage_prob(stagetrain, sop, sop_bin_divide)
Inputs:: stagetrain : 1xN double - interpolated hypnogram at the resolution of sop – required sop : 1xN double - feature value per sample (e.g., SOpower) – required sop_bin_divide : 1xB double - bin edges along the feature axis – required
Outputs:: stage_prop : Bx5 double - per-bin stage proportions [N3, N2, N1, REM, Wake] timestamps : 1xB double - bin centers (useful for overlaying with the feature axis)

Notes

Each bin collects samples whose sop falls strictly between consecutive edges; the histogram over stage values 1..5 is normalized to 1 per bin.
