The only difference will be in the type of data. Credit scoring use mostly panel data, however it will be handled solely with time series in this paper.doi:10.1007/s11123-012-0276-0Hruška, Jurajlogistic regression; technical analysis; moving averages; automated trading...
A logistic regression model is a statistical model that is used to predict the probability of a binary outcome based on one or more predictor variables. It is a generalization of the classical linear regression model and is commonly used in practice for interpreting the relationship between predicto...
利用Logistic 回归模型和ISM 解释结构模型,基于575 份调查问卷数据,分析定西市马铃薯技术扩散过程中,影响农户采用行为的显著因素,探讨各个因素之间的层次关系。结果表明:① 农户采用马铃薯种植新技术主要受到农户自身变量、行为认知变量、生产经营变量、资源禀赋变量和环境特征变量五大类特征变量的影响;②Logistic 回归分析表明...
