Dear All,
Thanks for your continuous support and guidance through this forum. This
time, I have a query regarding errors in 'nlsem' package, which reads as
follows:
Error in if (abs(ll.old - ll.new) < convergence) run <- FALSE :
missing value where TRUE/FALSE needed
This errors comes after using following codes:
model2<- specify_sem(
num.x=6,
num.y=1,
num.xi=3,
num.eta=1,
xi="x1-x2,x3-x4,x5-x6",
eta="y1",
num.classes=1,
rel.lat = "eta1~xi1+xi2+xi3",
interaction="xi1:xi1,xi1:xi2,xi2:xi2,xi1:xi3,xi2:xi3,xi3:xi3")
set.seed(927)
start<-runif(count_free_parameters(model2))
fill_model(model2, parameters = start)
data<-SPEV[,-c(1:2)]
res2 <- em(model2, data, start, max.iter = 100, qml=FALSE,
verbose=FALSE, convergence = 1, neg.hessian=TRUE,
optimizer=c("nlminb", "optim"))
This is to inform that these codes work well for one set of data
without error, but with the another dataset shows error.
I will be thankful to you for your valuable guidance.
Thanking you.
