The pseudo r2
Webb18 mars 2016 · The literature proposes numerous so-called pseudo-R 2 measures for evaluating “goodness of fit” in regression models with categorical dependent variables.Unlike ordinary least square-R 2, log-likelihood-based pseudo-R 2 s do not represent the proportion of explained variance but rather the improvement in model … Webb5 apr. 2024 · Pseudo-R2: 0.079: 0.156: 0.059: 0.098: 0.088: Notes: Attorney quality and invention quality are normalized to mean = 0 and standard deviation = 1. = bootstrap standard errors. Regression estimates are based on separate regression of each patent office's decision.
