In modeling using logistic regression, the appropriate transformations on continuous variables are necessary to optimize themodel predictiveness. The purpose of this paper is to demonstrate a method to automatically generate univariate plots for each input variable so that users can visually detect ...

因变量Y可以是连续型变量（continuous variable），比如血药浓度、肾小球滤过率等，此时可以用线性回归的...
Poisson regression, also known as a log-linear model, is what you use when your outcome variable is a count (i.e., numeric, but not quite so wide in range as a continuous variable.) 当你的因变量是单位时间某事件的发生次数时你就应该考虑用泊松回归,比如你想研究的因变量是过去一个月病人发...
Additionally, as with other forms of regression, multicollinearity among the predictors can lead to biased estimates and inflated standard errors. The procedure is most effective when group membership is a truly categorical variable; if group membership is based on values of a continuous variable (...
one or more independent variables of metric or binary scale. As such it is different from linear regression in that it allows/requires the dependent variable to be binary (i.e., 0/1) variable, while in linear regression the dependent variable has to be of metric scale (i.e., continuous...
Machine learning generally involves predicting a quantitative outcome or a qualitative class. The former is commonly referred to as a regression problem. In the scenario of linear regression, the input is a continuous variable, and the prediction is a numerical value. When predicting a qualitative ...
