Hi all, 

I used the Growth curve model in lavaan and estimated defied parameters - part of the results as below. 

Is there a way to get the exact P value, more than 3 decimals?  For now the P value is displayed as 0.000.


Defined Parameters:
                   Estimate  Std.Err  z-value  P(>|z|)
slop_a         0.482        0.088    5.480        0.000

Many thanks in advance,
Zuo

You can use parameterestimates(mymodel)$pvalue if you want. Otherwise save parameterestimates to an object and extract what you need with desired precision.

That's because the default argument is nd=3.

summary(fit, nd = 6)
class?lavaan # see other arguments
