| Abstract: |
| The Statistical Method of Average Cumulative Inclusion Lag, a method for the statistics of database inclusion time lag, can be used easily for the statistics of cumulative lag in a long period of time, and eliminates errors caused by short statistical period in manual sampling. The results of the statistics can be used for the evaluation of different retrieval tools in the same field. 2 formulas. 3 tabs. 3 refs. |
