WebOct 8, 2024 · Introduction to Bootstrapping in Statistics with an Example By Jim Frost 106 Comments Bootstrapping is a statistical procedure that resamples a single dataset to create many simulated samples. This process allows you to calculate standard errors, construct confidence intervals, and perform hypothesis testing for numerous types of sample … WebReasonable robustness checks ( Simonsohn et. al., 2024) are (i) sensible tests of the research question, (ii) expected to be statistically valid, and (iii) not redundant with other specifications in the set. The set of feasible robustness checks is defined by all the specifications that can be computationally reproduced.
