Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Could anyone tell me what type of statistical test is used to estimate the parameters of the standard model?

I hear many particle physicists say, eg. "we have a 95% confidence that this quark mass falls between A and B" and what immediately comes to mind are the methods of statistical hypothesis testing like... z test or t test.

Any explanations or comments about the statistical analysis being done on the data that we get from colliders?

Thanks in advance!
