Linear regression is the most simplistic form of regression, utilized to evaluate a relationship between two variables, and is particularly useful for analyzing risk. A business might apply linear regression to determine that if there’s an increase in demand for a product; production would have to...

Poisson regression is different from linear en logistic regression, because it uses a log transformed dependent variable. For rates, defined as numbers of events per person per time unit, Poisson regression is very sensitive and probably better than standard regression methods....
使用拟合Poisson 模型可以了解一组预测变量和一个响应之间的关系,该响应描述事件在有限观测空间中出现的次数。Poisson 响应对事件进行计数,如在产品上检测到的缺陷数量。可以包括交互作用项和多项式项、执行逐步回归、拟合不同的链接函数以及使用检验样本或交叉验证来验证模型。例如...
