数据集NBASAL.RAW包含了美国篮球协会(NBA)269位运动员的薪水信息和职业统计。
(i)估计一个将每场得分(points)与加入联盟年数(exper)、年龄(age)、大学期间打球年数(coll)相联系的模型。包含一个exper的二次项，其他变量都应该以水平值形式加入模型。按照通常的格式报告结果。
(ii)保持大学打球年数和年龄不变，从加入联盟的第几个年份开始，在NBA打球的经历实际上将降低每场得分？这讲得通吗？
(iii)你为什么认为coll具有负系数，而且统计显著？(提示：NBA运动员在读完大学之前被选拔出，甚至直接从高中选出。)
(iv)有必要在方程中增加age的二次项吗？一旦控制了exper和coll之后，这对年龄效应意味着什么？
(v)现在将log(wage)对points，exper，exper2，age和coll回归。以通常的格式报告结论。
(vi)在第(v)部分的回归中检验age和coll是否联合显著。一旦控制了得分和资历，这对考察年龄和受教育程度是否对工资具有单独影响这个问题有何含义？

When Reginald Lindsay received a scholarship to Morehouse College in Atlanta, Georgia, what he wanted most was a good job with a good salary. But soon he became interested in the civil rights movement. At present he has a plan which he hopes will take him to Congress as a southern representative.Now in his first year at Harvard Law School, Reg is making careful plans. After earning his degree, he expects to return to the South to practice law among the poor. "I want to help them understand what their rights are and to help them achieve them," he says. Then he hopes to run for political office at the local and state level until he is ready to try for Congress.Reg grew up in a low-income Negro section of Birmingham, Alabama. Brought up by his grandparents after his parents were divorced while he was very young, Reg has been living through a period of far-reaching progress in race relations. In the summer of 1968 Reg himself became a good example of this progress when he became the first Negro student appointed to a special new program. The program introduces bright young students to the workings of the Georgia State government and encourages them to seek employment there after finishing their education. "I've been lucky," he says. "I seem to have been in the right place at the right time."
But luck is only part of Reg's story, for he has made the most of opportunities that came his way. He learned to read in kindergarten and began visiting the public library regularly to borrow books. His grandparents encouraged him, though neither of them had much education, and they bought him a set of encyclopedias. "I loved those books," he re- members. "I used to come downstairs before breakfast and read short articles. I enjoyed reading about famous men, and then I would pretend to be one of them. I guess it was partly a childish game and partly an escape. It wasn't too much fun to be a Negro when I was a kid."
While studying for his bachelor's degree at Morehouse College, Reg worked on several political campaigns helping candidates get elected to government offices. At the same time he maintained a "B" average while majoring in political science. He worked as a student advisor to earn extra money for his college expenses, and he was granted a scholarship for a year of study at the University of Valencia in Spain.With just two more years to complete at Harvard Law School, which also gave him a scholarship, Reg has made a good start on his professional career. He says, "The good life for me is the kind of life where I can find satisfaction in public service."
