Calculating a Bayes Factor for a Regression Coefficient
I'd like to conduct a Bayesian re-analysis of regression coefficients using only summary statistics. I know that JASP/Bayes Factor allows you to obtain a Bayes factor for the R^2 using summary statistics, but I have a few questions regarding a method for obtaining a Bayes factor for the regression coefficients themselves:
1) Is it valid to obtain the t-statistic used to evaluate the statistical significance of a particular regression coefficient, and use that to obtain a corresponding Bayes factor by using the JASP summary statistics module for a one-sample t-test (while subtracting the number of predictors from the degrees of freedom)?
2) If this approach is not valid, is there an alternative way to obtain a Bayes factor for a regression coefficient using only summary statistics?
Thanks in advance,
