Polynomial regressionRegression discontinuityUncertaintyIt is common in regression discontinuity analysis to control for third, fourth, or higher-degree polynomials of the forcing variable. There appears to be a perception that such methods are theoretically justified, even though they can lead to ...

When I open the Curve Fitting app in MATLAB, my dropdown menu for model types does not include the full list of expected options. The only options I see are "Custom Equation", "Interpolant", "Lowess", and "Polynomial". Why can I not select something like "E...

activities. The MVAR model is usually used to conceptualize temporal causality, where the cause affects the future. Unlike the conventional linear methods that mainly focus on linear MVAR models, the nCREANN method captures both linear and nonlinear dynamics of the information flow among cortical regi...
My main guess is that the assumption or underlying model differs between ca.jo and our function because the eigenvectors do not match closely enough given that the computation is just linear algebra. Sorry, something went wrong. Copy link ...
Let’s delve into regression first. Regression It is common for people to think everything is a linear regression problem, but this is not the case. Regressionalgorithmshave a very strict set of assumptions that have to be met in order for the final results to be statisticallyreliable(*Note...
Suppose that p(x/3)=x^2 + x + 1, what is the sum of all values of x for which p(3x)=7? Why the least-square natural choice for linear regression? Is the set S of all functions in C^2(R) satisfying the differential equation y'' + 4y = 0 a subspace of C^2(R)? why ...
There is an infinite set of hypotheses for a finite set of samples. For example, consider observations of two points of some single-variable function. It is possible to fit a single linear model and an infinite amount of periodic or polynomial functions that perfectly fit the observations....
Frankly, I don’t consider this is a very important result as there is never a true model. In reality, every model is wrong, so consistency is not really an interesting property.Cross-validation for linear models While cross-validation can be computationally expensive in general, it is very ...
