smalldemodata: Small demo dataset

In natbprice/tvdiff: Numerical differentiation of noisy, nonsmooth data

Description

A test dataset based on the function f(x) = |x-0.5| with Gaussian noise with a standard deviation of 0.05.

Usage

smalldemodata

Format

A data frame with 100 rows and 3 variables:

x

seq(0, 1, length.out = 100)

true

abs(x - 0.5)

obs

abs(x - 0.5) + rnorm(length(x), mean = 0 , sd = 0.05)
