Fit a monotonically increasing function
WebApr 27, 2024 · Hi guys, I'm new to this field of kernel estimation/smooth isotonic regression/smooth monotonic regression. I need to fit a model for my strictly monotonic data, I got lost with all the info online. more specifficaly, I have data set points , I know that the data is monoctonically increasing, no noise. and I'm looking for a function f suct that . WebNov 23, 2024 · 2. When we say (monotone) increasing it implies that the sequence is monotone for that reason the term "monotone" can be omitted. Usually we also distinguish. (monotone) strictly increasing when f n < f n + 1. (monotone) increasing when f n ≤ f n + 1. and. (monotone) strictly decreasing when f n > f n + 1. (monotone) decreasing when …
