Generate random draws from a set of quantiles, based on the empirical
cumulative density function
Usage
sample_qtls(n, probs, qtls)
Arguments
- n
integer, the number of draws to generate
- probs
numeric vector, the probabilities
- qtls
numeric vector, the quantiles for the probabilities
specified in probs
Value
a numeric vector, with random draws of the approximated distribution
underpinning the provided quantiles
Details
Based on the Inverse Transform Sampling technique, by sampling
random probabilities from a uniform distribution and interpolate (cubic)
the count samples from the percentiles provided by the user (taken as the
empirical cumulative density function)
Examples
sample_qtls(10,c(0.1,0.2,0.3),qtls=c(0.05,0.1,0.95))
