因变量是定性变量的情况如医学上的阴性和阳性，生存和死亡，消费现象中的购买行为发生还是不发生，金融现象中的IPO通过还是不通过等等。All the regression analysis variables we mentioned above are quantitative variables, but in real life, dependent variables are both quantitative and qualitative. Dependent variab...
The following query returns some basic information about the logistic regression model. A logistic regression model is similar to a neural network model in many ways, including the presence of a marginal statistic node (NODE_TYPE = 24) that describes the values used as inputs. This example quer...
Neil R.SmalheiserMD, PHD, inData Literacy, 2017 Logistic Regression Logistic regressionis a very popular type ofmultiple linear regressionthat can handle outcomes that are yes versus no rather thannumerical values. For example, a regularmultiple regression modelmight deal with age at death as an ...
北京协和医学院博士学位论文 据库中的酶切多肽的理论谱图进行比对,通过特定的打分算法,找到匹配最佳的多肽。 由于样品和实验原理的复杂性,质谱图带有很高的噪声,为后续的数据处理工作带来 了很大的难度。目前已有多种算法用来优化多肽的鉴定,但阳性和阴性的多肽鉴定仍 不能够被完美地区分。为了保证鉴定结果的可信,就...
In conventional logistic regression, interactions are typically ignored. We propose a model selection procedure by implementing an association rules analysis. We do this by (1) exploring the combinations of input variables which have significant impacts to response (via association rules analysis); (2...
For example, if being 10 years older doubled the risk of death, this is the effect of age that should be used for adjustment. In real life, true effects are typically unknown, and the analyst estimates the effect of age from the trial sample at hand. But this sample-based model ...

In order to improve the goodness of fit of the logistic and Gumbel distributions, many generalizations of these distributions have been studied in the literature. For example, Prentice (1976) proposed logistic type IV to model binomial regression data. Stukel (1988) proposed logistic regression model...
In Section 3, some new bivariate type versions using “Farlie-Gumbel-Morgenstern Copula”, “modified Farlie-Gumbel-Morgenstern Copula”, “Clayton Copula” and “Renyi’s entropy Copula” are obtained. In Section 4, we provided three applications to real data to illustrate the flexibility of the...
