This is the sixth in a series of lecture notes which, if tied together into a textbook, might be entitled "Practical Regression." The purpose of the notes is to supplement the theoretical content of most statistics texts with practical advice based on nearly three decades of experience of the author, combined with over one hundred years of experience of colleagues who have offered guidance. As the title "Practical Regression" suggests, these notes are a guide to performing regression in practice. This note begins by describing the problems that arise when variables are measured with noise. The note progresses to explain how to test for and correct heteroskedasticity. It also explains why it is necessary to adjust standard errors when working with grouped data.

As the title "Practical Regression" suggests, these notes are a guide to performing regression in practice. This note explains how to choose between log and linear specification.

James and Laura Wiggins had some decisions to make. Last year, James’s father had died of a stroke. Death was not instantaneous, however, and the man had lingered in hospital for several weeks in a coma. During this time, no one had been able to access James’s father’s bank accounts (which were registered in the father’s name only). This inability to access the accounts had caused James’s mother considerable economic hardship, which impressed upon James the value of a power of attorney (POA). To that end, James asked his lawyer to prepare a power of attorney for him and Laura. James wanted Laura to sign the documents that night.<br><br>Before signing, Laura had some reservations and a few questions she wanted James to answer. She didn’t understand how a POA worked. Was it the same as a will? She and James didn’t have a will. Would the POA satisfy both needs?

This is the tenth in a series of lecture notes which, if tied together into a textbook, might be entitled "Practical Regression."

As the title "Practical Regression" suggests, these notes are a guide to performing regression in practice. This note uses the theory of "supplier-induced demand" from health economics to illustrate key issues including reverse causality, the role of instrumental variables in establishing causality, and the characteristics of good instruments.

This is the eleventh in a series of lecture notes which, if tied together into a textbook, might be entitled "Practical Regression." The purpose of the notes is to supplement the theoretical content of most statistics texts with practical advice based on nearly three decades of experience of the author, combined with over one hundred years of experience of colleagues who have offered guidance. As the title "Practical Regression" suggests, these notes are a guide to performing regression in practice. Using an extended example on hospital lengths of stay, the note explains how to "deconstruct" a regression in order to parse out how each variable contributes to the overall result. Regression is viewed as an exercise in "benchmarking"-explaining why some observations in the data "outperform" or "underperform" others. The residual is viewed as a potential measure of managerial effectiveness, albeit one that must be treated with caution. The note provides step-by-step instructions for using regression for benchmarking.

During the night of September 14, 2008, a few hours before Lehman Brothers folded, Merrill Lynch declared defeat: it was acquired by Bank of America (BofA). Unsure of its ability to continue as a stand-alone entity, Merrill Lynch deliberately ended 90 years of independence. Before its buyout by BofA, Merrill Lynch was the world's largest and most widely recognized stockbroker. It dominated retail stockbroking with its army of 16,000 brokers around the world. At the start of 2008, Merrill Lynch, Goldman Sachs, Morgan Stanley, Lehman Brothers and Bear Stearns were the five largest stand-alone investment banks, with a combined total history of 549 years: within the span of six months, they would all be gone. Some observers wondered whether any early signs of the financial distress that the investment firm experienced in 2008 could be seen in the financial statements published in the years preceding the acquisition of this giant. In addition, was there value in evaluating the performance of the company from an angle other than that of operating results, which is typically used by financial analysts? Specifically would there be value in an assessment of the company's performance by scrutinizing the origin and use of its liquid assets for the years 2005, 2006 and 2007. Such an investigation has required focus on the statements of cash flows, including the need to: evaluate the cash situation at year-end;analyze cash flows provided (used) by operating activities;analyze cash flows provided (used) by investment activities;and, analyze cash flows provided (used) by financing activities.

Siddharth Kapoor, the Founder and CEO of H-Soft Mumbai, reflected on his meetings as he walked out of VC Ventures' offices in Mumbai. After a few months of intensely pitching his startup to several different investors, he finally had a term sheet in hand. Despite this huge milestone, Kapoor knew it was only the start of a long process of raising money. He only had three days to get back to Sharma and indicate whether he would like to initiate the diligence process. While he was familiar with some of the terms venture capital investors put into their contracts, many others were completely alien to him. Which terms were important? Which ones should he focus on negotiating? He also knew that money was only part of what the venture capital investors brought to the table. Was VC Ventures the right partner for his business? Kapoor knew he had a busy few days ahead of him as he thought through all of these questions before getting back to Vikram Sharma.

The analyst had become interested in S&W when the company announced the acquisition of Universal Safety Response, Inc. (USR). The USR deal represented a significant investment for S&W and therefore created an opportunity for the company to become either undervalued or overvalued by the market.
