Robust automatic jitter and smoothed bootstrap in R » Example2

The bootstrap distribution is “holy” and percentile confidence intervals are confined to the spikes (bias = −0.08, Percentile 95% CI = −0.79, −0.13), jitter amount = NULL had little effect, jitter amount = 0 is too smooth because the range (max(x) − min (x)) was inflated by outliers in the data (bias = −0.12, 95% CI = −0.7708, −0.0805), robust jitter has the narrowest confidence interval (bias = −0.09, 95% CI = −0.7597, −0.0776).
