Plotting Distribution of Bootstrapped Values in R As a data analyst, it’s often necessary to visualize the distribution of bootstrapped values to understand the variability and uncertainty associated with your results. In this article, we’ll explore how to plot the distribution of bootstrapped values in R using various methods. Understanding Bootstrapping Bootstrapping is a resampling technique used to estimate the variability of a statistic or a parameter. The basic idea is to resample the original data with replacement, calculate the desired statistic for each bootstrap sample, and then repeat this process many times (typically 1000-10000 times).
