UFO Data

What data have been gathered?

The data (NUFORC ufo-reports) were gathered from planetsig's ufo-reports github repository: https://github.com/planetsig/ufo-reports via command-line git.

Data Exploration:

The dataset is messy. Very messy. The first thing we've gotta do is take care of that index column. For some reason, the index column is set as an inconsistently formatted date-time string. First, we're going to want to tease that into its own column, and replace the index column with a 0-indexed list.

Questions to be asked:

Are there specific times and places when/where alleged UFO sightings were attested to with more certainty?

Operationalized as: Do certain keywords in the notes, such as "sure", "positively", "definitely", "absolutely", "certain", etc. appear more often in certain geographical locations and decades?

Modeling Approaches

• Logistic regression
