Rare Events

/ rymerben / Leave a comment
Some things don’t happen very often.  Rarity makes them interesting and important, but also cryptic.  Epidemiologists, insurers and bankers, the military, geographers, scholars of international relations and meteorologists all face important challenges in forecasting how likely rare events are to occur over a given period of time.  Rare events matter in fundraising too; major gifts are scarce, but important.  So how do we estimate the chance of big gifts occurring when only relatively few will be given across a supporter base? (Hint: it’s not via a heat map):

One popular method has been to use logistic regression, a statistical method used to illustrate how likely it is that one variable causes others to change in a given scenario. However, for various reasons, it can sharply underestimate the chance of rare events occurring, making it unreliable in forecasting.  However, a new approach being pioneered by Italian academics Raffaella Calabrese and Silvia Angela Osmetti may have some answers. They propose a new statistical method to account for situations where one comparison group is very small, hopefully bypassing the underestimation issue.  And another area (even more) remote from fundraising or marketing could offer some clues on gaining insight into rare events: namely, the study of civil wars.  A recent paper from Rob Blair, Chris Blattman and Angela Hartman describes how the use of a set of statistical methods including neural networks, random forests and ‘LASSO’, a kind of logistic regression, can help to gain insight into the likelihood of occurrence of civil war.  The paper presents three findings of interest: first, that all the methods used return results better than chance, (some are far better), and therefore have a good degree of predictive power.  Second, the simplest method (LASSO) gives some of the most accurate results (hopeful for the non-statisticians among us), and, third, initial results suggest some novel causes for conflict that previous literature had not highlighted.  These findings are partly based on important earlier work by Gary King and Langche Zeng, whose much-cited 2001 article is a key text in the rare event literature.  This research is a step in the right direction, although obviously does not solve the thorny issue of using data and statistics to predict rare events.

Information is the lifeblood of modern organisations, and philanthropy can suffer due to a lack of robust, granular management information on forecasted donor value.  But this should not be an excuse not to try to understand the predictors of major gifts.  The studies mentioned above work with far more difficult and complex environments than fundraising, and are making headway in their forecasting efforts.  It is still very early days in using probabilities to gauge the effects of specific solicitation or cultivation activities on donations.  While developments in arcane statistics journals will obviously not raise more money in isolation, improving our data-driven prospecting and fundraising probably will.  And when major gifts are less rare, the models will predict them better, making them even less rare, meaning the models will predict them better…

Lucy Gower interview: “You can’t do good innovation without insight”

Lucy is an innovation expert who works with charities to improve their ability to innovate and raise funds.  She tweets at @LucyInnovation.

Lucy makes the point that innovations are unlikely to give returns within financial year; so the pipeline of new innovations needs to a) be well populated and b) have a multi-year strategy/budget.  The challenge isn’t to not ‘fail’, it is to make your innovation process robust enough to withstand ‘failure’, for senior leadership to make failure something people are happy to discuss and mull over, and to spread the attitude that discussing failure is not a bad thing.  It is the case though that we become invested in our ideas, and sometimes lose our willingness to accept that something isn’t working.

Every charity wants to innovate.  However, leadership and culture are critical.  A culture of innovative practice doesn’t come about without examples from the top, especially as it can be difficult for more junior staff to say “that project I worked on absolutely tanked” if they are worried that it will be perceived badly by their superiors.  The whole organisation must be behind a change to innovative practices or it is likely to fail.  We discussed the example of shoe company Zappos, who pay staff to leave if they are not happy.  As founder Tony Hsieh says in a fascinating article about his sale of the business to Amazon, “I believe that getting the culture right is the most important thing a company can do”.

For prospect research and insight, its interesting to consider the role of “translators”.  These are the people in organisations who draw out the narratives from information and present the story.  For researchers, this is a key skill, and is really important in modern, information-rich/time-poor organisations.  And Lucy is clear that “you can’t do innovation without insight”.  Building and using a base of evidence for new products and projects, and evaluating existing work, is absolutely essential in the innovation process.  While “creativity means not copying“, creativity and innovation rely on learning from experience and incorporating this learning into future work.
