what is the purpose of bias in data mining which of the following is an example of a bias correction for effect size analysis? which function is biased to estimate effect size? why is bias correction used in data mining is bias correction necessary why are effect sizes biased what is the bias correction in effect size estimation how to appoint bias correction for effect size when determining optimal effect size, you have to estimate the effect size of what is the best way to estimate effect size? how to determine effect size which of the following is an example of a positive bias? what is the problem with an effect size? how to find optimal treatment what is the function of the effect size function is there bias for effect size how do you find the optimal response and find the optimal treatment naive approach to estimating effect size is there a bias correction for effect sizes in data mining can you predict effect size of a treatment using a bias correction
