I have my2pl as ltm data and my3pl as tpm data.  

    anova(my2pl,my3pl)  
    Likelihood Ratio Table  
    AIC      BIC  log.Lik   LRT df p.value  
    my2pl 16317.52 16630.39 -8078.76                   
    my3pl 16299.71 16769.00 -8029.85 97.81 40  <0.001  

Shall I use ltm or tpm model based on this anova?
