I'm working with modindices
command in R
, lavaan
package:
modindices(fit,power=TRUE,delta=0.1,alpha=0.05,high.power=0.75)
Could someone describe what different notions in decision column of modification indices mean? for example (i),*****,epc?
Output:
127 F5 =~ V78 17.165 -0.513 -0.513 0.1 0.378 0.094 ***
128 F5 =~ V47 10.654 0.400 0.400 0.1 0.361 0.092 ***
129 F5 =~ V79 1.036 0.126 0.126 0.1 0.331 0.089 (i)
130 F5 =~ V60 16.374 -0.269 -0.269 0.1 1.307 0.208 ***
131 F5 =~ V75 0.000 0.001 0.001 0.1 1.309 0.208 (i)
132 F5 =~ V62 2.331 0.102 0.102 0.1 1.307 0.208 (i)
133 F5 =~ V51 10.848 0.227 0.227 0.1 1.252 0.201 ***
Based on the function's code, it appears that:
***
means that the modification index is significant and the power is not high.epc
means that the modification index is significant and the power is high.(i)
means that the modification index is not significant and the power is not high.The cut-offs for significance and high power are set with the
alpha
andhigh.power
parameters, respectively.
