This interactive shows the results of a linear regression model to predict the publication date (or date written) of book-length works published between 1760 and 1990. Many of the texts belong to market genres such as horror/gothic, mystery/crime and science fiction. Each point represents a text, and its position along the x-y axis represents the predicted year and the actual year. The orange line projected through this visualization represents a one-to-one ratio of the predicted value and the metadata value. In other words, the closer a point is to this line, the more accurate the model predicted its date. Similarly, a point farther away from the line represents a less accurate prediction or, in some cases, an inaccurate date in the original metadata.
