In that post, I provided some background on Functional Analysis, the mathematical theory that makes FDA possible, identified FDA resources that might be of interest R users, and showed how to turn a series of data points into an FDA object. In this post, I will pick up …
WebOverview. In regression modeling when we include a continuous predictor variable in our model, either as the main exposure of interest or as a confounder, we are making the assumption that the relationship between the predictor variable and the outcome is linear. In other words, a one unit increase in the predictor variable is associated with a ... WebJul 19, 2024 · 6. BSpline allows you to construct a b-spline if you know its coefficients. If you want to fit these coefficients, you'll have to use something like splrep. The alternative would be to do a linear regression on the BSpline.basis_elemement s, but it's almost surely better to use splrep for your use-case.
