between 1986 and 1999. The data was gathered for this experiment was from the Storm Prediction Center National Tornado Archive. The researchers determined the installation and use date of the Doppler radars. Simmons and Sutter created dummy variables, then they used a treatment variable, according to the installation dates of the Doppler radars. Simmons and Sutter created dummy variables that included length of time the tornado was on the ground, season in which the tornado occurred, day, and whether the tornado occurred in the evening or at night. A dummy variable is a fake variable used to represent something with levels or categories. One problem with the methods is that the statistics coming from this experiment are not useful considering they are dummy variables these methods will help someone with a project on tornadoes and death rates by giving them another place to look for tornado
