Commentary/Chow: Statistical significance
I disagree with several of Chow’s traditional descriptions and justifications of null hypothesis testing: (1) accepting the null hypothesis whenever p . .05; (2) random sampling from a population; (3) the frequentist interpretation of probability; (4) having the null hypothesis generate both a probability distribution and a complement of the desired conclusion; (5) assuming that researchers mus...
متن کاملInvited commentary: Surveilling surveillance--some statistical comments.
The authors’ approach offers a movement from statistical testing to statistical modeling for disease surveillance. Traditionally, statistical methods for surveillance tend to evolve from a hypothesis-testing framework, wherein one “detects” an outbreak (anomaly, cluster, etc.) as a “statistically significant” departure from a null hypothesis defined as the lack of an outbreak (e.g., constant ag...
متن کاملStatistical Problems with Statistical-based Intrusion Detection
In 1987 Dorothy Denning wrote in her seminal paper “An Intrusion-Detection Model” the following words: “exploitation of a system’s vulnerabilities involves abnormal use of the system; therefore, security violations could be detected from abnormal patterns of usage.” With these words, Denning kicked off 20 years of research, development, and publications in anomaly-based intrusion detection, whe...
متن کاملNonparametric statistical inverse problems
We explain some basic theoretical issues regarding nonparametric statistics applied to inverse problems. Simple examples are used to present classical concepts such as the white noise model, risk estimation, minimax risk, model selection and optimal rates of convergence, as well as more recent concepts such as adaptive estimation, oracle inequalities, modern model selection methods, Stein’s unb...
متن کاملCommentary: feeding problems: an ecological perspective.
teractive process that varies across children and is embedded in multiple social levels, extending from the family through cultural factors. The ecological model is based on systems theory, in which changes in any one component of the model affect all other components. Children are conceptualized as active contributors within their primary context-the family. At a broader level, feeding is infl...
