| Abstract: | There is considerable pressure on charities and voluntary organisations, both to reduce ‘wasted’ expenditure on administrative costs and unwanted mailings, and to deliver more and better services from their voluntary support. Modern tools allow organisations to tailor mailing requirements to individual needs easily and cheaply. Charities need to become ever more efficient: improving the response rates, while reducing overall expenditure on money‐raising activities. Simple means and summary statistics can be seriously biased and misleading for this type of data. Survival analysis is a good, sound and flexible tool to analyse length of time to next donation and membership data. This can lead to a better understanding and more efficient use of the available budgets. Copyright © 2001 Henry Stewart Publications |
