Previous studies find that small stocks have higher average returns than large stocks, and the difference between the returns can not be accounted for by the systematic risk, b. In my analysis of Compustat and CRSP data from 1976 to 1995, and simulation experiments based on the data, I find the size effect can be largely explained by data truncation that is caused by survival. Small stocks’ ret...

Evidence is presented for a systematic text-length dependence of the power-law index γ of a single book. The estimated γ values are consistent with a monotonic decrease from 2 to 1 with increasing text length. A direct connection to an extended Heap’s law is explored. The infinite book limit is, as a consequence, proposed to be given by γ = 1 instead of the value γ = 2 expected if Zipf’s law is...

This study evaluated 2 ELT textbooks (Four Corners, Book 2 and Four CornersBook 3) drawing on Bloom’s revised taxonomy (BRT); it examined the extent towhich these ELT textbooks could demonstrate the 6 cognitive categories of the BRT(i.e., remembering, understanding, applying, analyzing, evaluating, and creating) intheir activities. To this end, content analysis was done to obtain the frequency ...

Performance evaluations in Probabilistic Information Retrieval are often presented as Precision-Recall or PrecisionScope graphs avoiding the otherwise dominating effect of the embedding irrelevant fraction. However, precision and recall values as such offer an incomplete overview of the information retrieval system under study: information about system parameters like generality (the embedding ...
