Just found your content and I find it far clearer than most other creators who try to explain similar concepts. Good job

hi mike, I have a question, that is, lets say i have data points, now I made a curve a manually (lets imagine it is possible ) joining each points one by one. it will give a some crooked curve obviously, now if I calculate BIC for this crooked curve will it give minimize value ?

Mike! I really enjoyed this insightful video. What method do you regard as the best when incorporating noise for polynomial functions?
@mikexcohen1
@mikexcohen1 3 года назад
Hi Philipp. There are many ways to simulate noise, depending on the goal. The easiest thing to do is to use white noise (randn in MATLAB or np.random.randn in Python) with a suitable standard deviation.
@philippu1455
@philippu1455 3 года назад
​@@mikexcohen1 Thank you for the reply. What I am looking at is a neural network that approximates a polynomial given x values as input and their associated function values (y) as the label. I want to test the robustness of the model by adding noise to the function values of the training data. Would you say that the use of a normal distribution with a suitable standard deviation and the original, "true" y as the mean is appropriate for this endeavor?

What is your nulhypothesis and alternative hypothesis when you have a polynimial term in your regression when we are doing a t-test for each variable? Imagine you have y = b1 + b2 age + b3 age ^2? And you think that age has a negative effect on y over time?
@mikexcohen1
@mikexcohen1 3 года назад
The null hypothesis of regressors in a model is always the same: That the coefficient (the beta value) is statistically indistinguishable from zero.

shouldn't natural log be ln? I though log is base 10 log
@mikexcohen1
@mikexcohen1 3 года назад
Yikes! Yes, you're correct, and it's a bit of a typo there. I guess I was mixing code and math while writing out that equation. Anyway, my apologies for the confusion, and good catch!

If memory serves, in some math books, e is the default for a log base instead of 10, i.e. "log" is used for "ln".
