Problem: (CNN) -- Two former presidents reflected on their greatest regrets in office Monday, each looking back to issues that continue to plague the nation years later.

Former presidents and political rivals Bill Clinton and George H.W. Bush now share philanthropic efforts.

Former Presidents George H.W. Bush and Bill Clinton appeared together at a question-and-answer forum before the National Automobile Dealers Association in New Orleans, Louisiana.

Asked his biggest regret after leaving office, Bush said he now wonders whether he should have tried to get Saddam Hussein to leave office at the end of the first Gulf War in 1991.

He told the gathering, "I've thought a lot about it, but at the end of Desert Storm, the question was should we have kind of kept going on that road to death and all this slaughter until Saddam Hussein showed up and laid his sword on the table, surrendered. And the common wisdom was he wouldn't do that."

But he said a conversation with an FBI agent who interrogated Saddam after he was captured has made him reconsider.

Bush recalled their talk, "I said, 'What if we just say he has to come to surrender, would he have done it?' And this guy said, 'I'm absolutely convinced he would have.' My experts tell me he wouldn't have."

Bush said, "We ended it the way we said we would" as a military success, but noted a cleaner ending "would have been perfect."

He added, "If we had tried to get Saddam Hussein to come and literally surrender and put his sword on the table, I think it might have been avoided some of the problems that we did have in the future from him."

Problem: CHAPTER XI

Marie and Victor

"Are you taking me to the girls, Harry?"

"No," Harry said. "It would not be safe to do so. There are already suspicions, and they have been denounced."

Marie gave a cry of alarm.

"I have managed to suppress the document, Marie, and we start with them in a day or two. Still it will be better for you not to go near them. I will arrange for you to meet them to-morrow."

"Where am I going, then?"

"You are going to the house of a worthy couple, who have shown themselves faithful and trustworthy by nursing a friend of mine, who has for nearly six months been lying ill there. You will be perfectly safe there till we can arrange matters."

"But if Robespierre has signed my release, as they said, I am safe enough, surely, and can go where I like."

"I think you will be safe from re-arrest here in Paris, Marie, because you could appeal to him; but outside Paris it might be different. However, we can talk about that to-morrow, when you have had a good night's rest."

Harry did not think it necessary to say, that when Lebat was missed it would probably be ascertained that he was last seen leaving La Force with her, and that if inquiries were set on foot about him she might be sought for. However, Marie said no more on the subject, quite content that Harry should make whatever arrangements he thought best, and she now began to ask all sorts of questions about her sisters, and so passed the time until they were close to the Place de Carrousel; then Harry called Jacques to stop.

Problem: Econometrics is the application of statistical methods to economic data and is described as the branch of economics that aims to give empirical content to economic relations. More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference". An introductory economics textbook describes econometrics as allowing economists "to sift through mountains of data to extract simple relationships". The first known use of the term "econometrics" (in cognate form) was by Polish economist Pawe Ciompa in 1910. Jan Tinbergen is considered by many to be one of the founding fathers of econometrics. Ragnar Frisch is credited with coining the term in the sense in which it is used today.

The basic tool for econometrics is the multiple linear regression model. Econometric theory uses statistical theory and mathematical statistics to evaluate and develop econometric methods. Econometricians try to find estimators that have desirable statistical properties including unbiasedness, efficiency, and consistency. "Applied econometrics" uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analyzing economic history, and forecasting.

The basic tool for econometrics is the multiple linear regression model. In modern econometrics, other statistical tools are frequently used, but linear regression is still the most frequently used starting point for an analysis. Estimating a linear regression on two variables can be visualized as fitting a line through data points representing paired values of the independent and dependent variables.
