The models we discussed are models that are linear in parameters; variables Y and Xs do not necessarily have to be linear The price elasticity of demand~the log-linear models The rate of growth~semilog model Functional forms of regression models which are linear in parameters, but not necessarily linear in variables:

Optimal Commodity Taxation Assume that the goal is to finance expenditures with a minimum of excess burden. Assume lump sum taxes are infeasible 3 commodities: Good X. Y, and leisure

logistic回归为概率型非线性回归模型,是研究分类观察结果(y)与一些影响因素(x)之间关系的一种多变量分析方法

一、含参无穷积分: 1.含参无穷积分:函数f(x,y)定义在[a,b]×[c,+∞)上([a,b]可以是无穷区间).以I(x)=f(xy)dy为例介绍含参无穷积分表示的函数I(x)
