Abstract: caterpillar takes a set of estimates and est standard errors se, along with a unique identifier id for each estimate. The estimates may represent the effects of different programs (as in von Hippel & Bellows, 2017) or the results of different studies (as in a meta-analysis). caterpillar outputs a "caterpillar plot" containing point estimates (sorted in ascending order), along with 95% pointwise confidence intervals, Bonferroni-corrected 95% confidence intervals, and an estimate of the null distribution. The null distribution represents what the distribution of estimates would look like under homogeneity -- i.e., if there were no differences between the effects, and the estimates differed only because of random estimation error.
