Using devices such as Jawbone Up, Nike FuelBand, and Fitbit it is now possible to collect a large amount of data about personal activity relatively inexpensively. These type of devices are part of the quantified self movement – a group of enthusiasts who take measurements about themselves regularly to improve their health, to find patterns in their behavior, or because they are tech geeks. One thing that people regularly do is quantify how much of a particular activity they do, but they rarely quantify how well they do it. In this project, your goal will be to use data from accelerometers on the belt, forearm, arm, and dumbell of 6 participants. They were asked to perform barbell lifts correctly and incorrectly in 5 different ways. More information is available from the website here: http://groupware.les.inf.puc-rio.br/har

This analysis investigates the impact of natural disasters—such as tornadoes, avalanches, and thunderstorms—on the U.S. economy and public health. Using data from the U.S. National Oceanic and Atmospheric Administration (NOAA) Storm Database, the study covers events from 1950 to 2011 to identify which types of natural events have caused the most significant harm.

In this reproducible research I've examine how various macroeconomic factors—such as capital flows, interest rates, fiscal/trade balance, volatility indices (VIX), oil prices, and GDP growth—impact the movement of the Indian Rupee.
