MIMIC includes the following table summary statistics:
| Table Statistic | Description |
|---|---|
Sum | Indicates the sum total of the values returned in the answers. |
Average | Indicates the average of the data for a column. |
Average (+) | Indicates the average of all the values in the answers. |
| Average (-) | Indicates the average of the negative answers to the query. |
Percent (+) | Percent positive. Indicates the number, as a percentage of the total number of occurrences, of positive answers to the query |
| Percent (-) | Percent negative. Indicates the number, as a percentage of the total number of occurrences, of negative answers to the query. |
| Maximum | Indicates the maximum of all the query answers. |
| Minimum | Indicates the minimum of all the query answers. |
| Std Deviation | Measures the mean deviation from the average of the answers. This can be a particularly valuable tool to interpret the answers to the query. For example, if the average return on a query is 3%, but the Standard Deviation on that is 10%, then it indicates a poor signal. It is best to have a standard deviation that is lower than the absolute value of the average value returned in the query. |
| Zstat | Indicates the Z-score of the results. This measures the goodness of the average. |
| Variance | This is related to the standard deviation calculation, which is actually the square root of the variance. |
| Last | Repeats the last value of the column data. |
