求问计量经济学和统计学问题
楼主在做作业的时候遇到一个很奇怪的题目.
请说出以下科目的作用,还给了一个例子:“ordinary least squares - useful in the development of linear economic models”.一共4个小问,【要求用和例子相同的方法表述】.
1.Hypothesis Testing (confidence and prediction intervals) -
2.Maximum Likelihood Estimation -
3.Multicollinearity,Heteroscedasticity and Autocorrelation -
4.Time Series Regression -
求问计量经济学和统计学问题楼主在做作业的时候遇到一个很奇怪的题目.请说出以下科目的作用,还给了一个例子:“ordinary least squares - useful in the development of linear economic models”.一共4个小
1. Hypothesis Testing (confidence and prediction intervals) -useful in judgement of whether the variables are significant;
2. Maximum Likelihood Estimation -another kind of estimation method that can be used in almost all sorts of econometrics models;
3. Multicollinearity, Heteroscedasticity and Autocorrelation -three common phenomena that violate the classical linear hypothesis;
4. Time Series Regression -useful in regressions which use time series data
这种题目大答案并不固定,只是检验一下初学者对这些名词的掌握程度而已.
