About this Dataset

Baseball

Context

Try to find the best predictors indicative of a home run, reported as log loss

Log Loss quantifies the accuracy of a classifier by penalizing false classifications.
Minimizing the Log Loss is equivalent to maximizing the accuracy of the classifier.

Content

Data set adapted from SLICE Competition Season 01 Episode 09 https://www.kaggle.com/c/sliced-s01e09-playoffs-1

These are only 2 hour competitions so time is limited. Here we can use the data set and take more time for analysis.

Acknowledgements

Adapted largely from David Robinson on YouTube. His modeling techniques are greatly appreciated in traversing the tidyverse()

Inspiration

Try to find the best predictors indicative of a home run, reported as log loss

Numeric predictors, categorical predictors, hybrid, how low can we go?
