Hi there, I used the rlm() function for doing a robust estimation based on M-estimates. Obviously, you only get the estimate, standard error and t- value by implementing this rlm() function. So, how can I say if a coefficient is statistical significant without the presence of a p-value? Thanks in advance! -- View this message in context: http://r.789695.n4.nabble.com/Statistical-significance-in-robust-estimation-rlm-tp4650275.html Sent from the R help mailing list archive at Nabble.com.
