Group Size and Conformity in Charitable Giving: Evidence from a Donation-Based Crowdfunding Platform in Japan

Social Science Research Network

The main variables are the modal amount among the preceding five donations and their appearance along the sequence. ...
Using data for 9,989 donations and exploring the model propounded by Smith et al. (2015), we construct variables to explain information a donor sees on the webpage. ...
This result implies that subsequent donors could recognize that many previous donors contributed the same amount, when multiple modal donations appear not only at no interval but also at some intervals ...

Through evaluations, we compare the utility of DeepGAN and DeepNAG against two alternative techniques for training five recognizers using data augmentation over six datasets. ...
We find that DeepNAG outperforms DeepGAN in accuracy, training time (up to 17x faster), and realism, thereby opening the door to a new line of research in generator network design and training for gesture ...

Since it is practically impossible to use the data of all possible noise conditions, we use only speech data for a few sampled conditions. ...
To increase reliability of the experiments, we use the jackknife method; the data of 56 speakers are divided into four groups and we repeat the experiment with the data of the three groups (42 speakers ...

In this case, two small samples might underestimate complementarity by yielding the same few common species, missing many rare species that would differentiate the sites in a larger sample.) ...

First, we show that raw agreement rates disregard agreement that occurs by chance and do not reliably capture how participants distinguish among referents. ...
We also demonstrate how to use common resampling techniques to support statistical inference with interval estimates. ...
