My question is about the "Signif. codes" , the output when I run


matcoef =cbind(fit$par, se.coef,tval,2*(1-pnorm(abs(tval))))

dimnames(matcoef)=list(names(tval),c("Estimate","Std.Error","t
value","pr(>|t|)"))

cat("\nCoefficient(s):\n")


printCoefmat(matcoef, digits=4, signif.stars = TRUE)


Coefficient(s):


     Estimate Std.Error t value pr(>|t|)

[1,]  -0.3941    0.7170 -0.5497    0.583

[2,]  -0.4278    0.1242 -3.4450    0.001

[3,]  26.9080    5.2271  5.1478    0.000


---------------------------------------------------------------------------------------------------

Signif. codes:  0 *** 0.001 ** 0.01 * 0.05 . 0.1   1




My problem is the pr(>|t|) doesn't show signif.stars

Does this means my data has problem?


Thanks
