0, so that individual scientists cannot precisely manipulate the score to be above or below the threshold. This assumption is valid in our setting, because the scores are given by external reviewers, and cannot be determined precisely by the applicants. To offer quantitative support for the validity of our approach, we run the McCrary test 80 to check if there is any density discontinuity of the running variable near the cutoff, and find that the running variable does not show significant density discontinuity at the cutoff (bias = ?0.11, and the standard error = 0.076).
Together with her, these types of overall performance verify the primary presumptions of fuzzy RD means
To understand the effect of an early-career near miss using this approach, we first calculate the effect of near misses for active PIs. Using the sample whose scores fell within ?5 and 5 points of the funding threshold, we find that a single near miss increased the probability to publish a hit paper by 6.1% in the next 10 years (Supplementary Fig. 7a), which is statistically significant (p-value < 0.05). The average citations gained by the near-miss group is 9.67 more than the narrow-win group (Supplementary Fig. 7b, p-value < 0.05). By focusing on the number of hit papers in the next 10 years after treatment, we again find significant difference: near-miss applicants publish 3.6 more hit papers compared with narrow-win applicants (Supplementary Fig. 7c, p-value 0.098). All these results are consistent with when we expand the sample size to incorporate wider score bands and control for the running variable (Supplementary Fig. 7a-c).
In regards to our attempt of tests method, we apply an old-fashioned treatment method since revealed however text (Fig. 3b) and you can upgrade the entire regression analysis. I recover again a significant effectation of early-field setback to the chances to create strike files and mediocre citations (Secondary Fig. 7d, e). To own hits each capita, we discover the outcome of the identical advice, additionally the insignificant distinctions are most likely due to a lesser decide to try size, providing suggestive proof on feeling (Second Fig. 7f). Finally, to help you take to new robustness of your own regression results, we then regulated almost every other covariates including publication seasons, PI sex, PI competition, place reputation as measured by the level of winning R01 honors in identical months, and PIs’ previous NIH sense. We retrieved a similar show (Second Fig. 17).
Coarsened particular coordinating
To further eliminate the effect of observable items and combine the fresh robustness of one’s performance, we working the official-of-artwork strategy, we.e., Coarsened Real Coordinating (CEM) 61 . The fresh matching approach after that ensures the latest similarity between slim victories and near misses ex ante. Brand new CEM algorithm pertains to around three methods:
Prune about study place the fresh devices in just about any stratum one do not are a minumum of one addressed and something handle device.
Following the algorithm, we use a set of ex ante features to control for individual grant experiences, scientific achievements, demographic features, and academic environments; these features include the number of prior R01 applications, number of hit papers published within three years prior to treatment, PI gender, ethnicity, reputation of the applicant’ institution as matching covariates. In total, we matched 475 of near misses out of 623; and among all 561 narrow wins, we can match 453. We then repeated our analyses by comparing career outcomes of matched near misses and narrow wins in the subsequent ten-year period after the treatment. We find near misses have 16.4% chances to publish hit papers, while for narrow wins this number is 14.0% (? 2 -test p-value < 0.001, odds ratio = 1.20, Supplementary Fig. 21a). For the average citations within 5 years after publication, we find near misses outperform narrow wins by a factor of 10.0% (30.8 for near misses and 27.7 for narrow wins, t-test p-value < 0.001, Cohen's d = 0.05, Supplementary Fig. 21b). Also, there is no statistical significant difference between near misses and narrow wins in terms of number of publications. Finally, the results are robust after conducting the conservative removal (‘Matching strategy and additional results in the RD regression' in Supplementary Note 3, Supplementary Fig. 21d-f).
