Lab 4 Interpretation help #62

Closed midupree closed 4 years ago

midupree commented 4 years ago

@LucyMcGowan I am having some issues sorting out the interpretation questions, probably because I am trying to refamiliarize myself with the material. I did most of my coding before I left for break and have been struggling to remember what does what and how I did it! For example, where do we find our chosen lambda and the test root mean squared error? I've attached my coding for question 4 as a reference. Once I understand what I did I'm sure I'll be ready to continue on with the other questions! Thanks, Miriam

Penalty is your lambda value. Mean is the average RMSE for each penalty

midupree commented 4 years ago

@LucyMcGowan so do I need to report each Mean? Or just average them?

LucyMcGowan commented 4 years ago

The instructions are to report the penalty that gives the best (smallest) RMSE, so just report that one.

Thank you @LucyMcGowan! So with Tune as our set penalty, that allows us to vary our lambda values, testing potentials of 0 and 10? That is what I interpreted from the slides.

midupree commented 4 years ago

@LucyMcGowan Would we report our chosen lambda value as varying between 0-10? Just need to fully understand this before I turn in my lab. I couldn't find much information about it in the tidy models slides. Thanks

Yes! Sorry I missed your question before
