The book explores topics such as logistic discrimination and generalised linear models, and builds upon the relationships between these basic models for continuous data and the analogous log-linear and logistic regression models for discrete data. It also carefully examines the differences in model ...

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...
LinearRegression的准确性 线性回归 线性回归的主要思想就是通过历史数据拟合出一条直线,用这条直线对新的数据进行预测,其公式如下: 这里的 ε 也就是模型和实际数值之间的误差值,根据中心极限定理(许多独立随机变量组合会符合高斯分布),我们可以接着假设误差项符合高斯分布:...
