Crisis Planning: Increasing Effectiveness, Decreasing Discomfort

Increasing Fundraising Success by Decreasing Donor Choice∗

Suggested contributions, membership categories, and discrete, incremental thank-you gifts are devices often used by benevolent associations that provide public goods. Such devices focus donations into discrete levels, thereby effectively limiting the donors’ freedom to give. We study the effects on overall donations of the tradeoff between rigid schemes that severely restrict the choices of con...

Partitioning Permutations into Increasing and Decreasing Subsequences

Increasing and Decreasing Subsequences and Their Variants

We survey the theory of increasing and decreasing subsequences of permutations. Enumeration problems in this area are closely related to the RSK algorithm. The asymptotic behavior of the expected value of the length is(w) of the longest increasing subsequence of a permutation w of 1, 2, . . . , n was obtained by Vershik-Kerov and (almost) by Logan-Shepp. The entire limiting distribution of is(w...

Increasing and Decreasing with Fuzzy Time Series

There is a significant problem associated with the fuzzy time series. That is a strict increasing and decreasing case. Under the discussion case, fuzzy time series model arise a continuous increasing/decreasing forecasting value. From the illustrative example, we can see that our definition not only define the trend of the fuzzy numbers that represent the linguistic values of the linguistic var...

Preponderantly increasing/decreasing data in regression analysis

Abstract. For the given data (wi, xi, yi), i = 1, . . . , n, and the given model function f(x;θ), where θ is a vector of unknown parameters, the goal of regression analysis is to obtain estimator θ∗ of the unknown parameters θ such that the vector of residuals is minimized in some sense. The common approach to this problem of minimization is the least-squares method, that is minimizing the L2 n...
