0 perc_obs_retained in all min_PDM_thresholds

[esaghy]

I have all 0s in perc_obs_retained column when running metadata$min_PDM_thresholds.

My dataset's parameters are:

• rows: 317
• columns: 56
• complete cases: 284
• highest proportion of missingness per variable: 1.9%
• fraction missingness: 0.003661559

My output for metadata$min_PDM_thresholds:
min_PDM_threshold perc_obs_retained
1 5 0
2 10 0
3 20 0
4 50 0
5 100 0
6 200 0
7 500 0
8 1000 0

Is the problem stemming from my dataset? Is it too small to do imputation on? Could I overcome the problem somehow?
