Preoperative HCO3-¶
Preoperative HCO3- (clinical table).
| Name in the dataset | preop_hco3 |
| Type | clinical |
| Stored in | clinical_data.csv |
| Unit | mmol/L |
Description¶
Pre-operative copy of a lab result; behaves like the lab data.
Measurement space¶
A vertical slice through the measurement space: how the true value is spread around any one recorded value. Its shape is uniform.
Time¶
This variable carries no time of its own in the dataset.
Value¶
| Model kind | uniform: single resolution; uniform over the rounding interval |
| Resolution | 0.1 mmol/L, nearest |
| Native step | 0.1 mmol/L |
| Anchor | nearest (convention) |
In this release¶
How wide the true-value distribution is, record by record, over 533 of 6,388 records (all clinical rows) that have one. Computed with the pinned model, aggregates only.
| Median | p10 to p90 | |
|---|---|---|
| Standard deviation | 0.0289 mmol/L | 0.0289 to 0.0289 mmol/L |
| 95% interval width | 0.095 mmol/L | 0.095 to 0.095 mmol/L |
| Mean minus recorded | 0 mmol/L | 0 to 0 mmol/L |
Anchor¶
Laboratory results rounded to the last reported digit; at most half the last digit. See what an anchor is and every variable's anchor.
