Common Domain Observability
Description
Generates samples of functions observed in a common domain in the center part of the domain. See Elías et al (2020).
Usage
commondomainPOFD(data, observability = NULL, pIncomplete = NULL)
Arguments
data |
functional data completely observed. pxn matrix being n the number of curves and p the number og evaluation points. |
observability |
mean observed proportion of the domain where each function is observed. |
pIncomplete |
number between 0 and 1 related to the proportion of curves that suffers partially observability. The default is 1 meaning that all the sample curves are partially observed. |
Value
a list containing two elements 1) a functional sample and 2) the same sample of functions but partially observed following one of the schemes described in the argument type.

Examples
data <- sapply(1:100, function(x) runif(1)*sin(seq(0, 2*pi, length.out = 200)) +
runif(1)*cos(seq(0, 2*pi, length.out = 200)))
