当你在Python代码中遇到错误 NameError: name 'mean_squared_error' is not defined 时,这通常意味着mean_squared_error这个函数在你的代码环境中没有被正确导入或者定义。以下是一些解决这个问题的步骤: 检查是否已导入mean_squared_error函数: mean_squared_error函数通常用于计算均方误差,是机器学习领域常用的一个损...

Alonzo and Pepe (2002) compared their estimating equations probability density function method (with empirical estimation of the false-positive rates) to the maximum likelihood approach of Dorfman and Alf (1969) and found that they had similar efficiency and mean squared error. So we should expect...
