If the x's that don't enter at the same time can be considered independent of

I have used PoLCA for this purpose, and not the e1071 package.
You should use a variety of fit indices to choose the number of classes. The
BIC may not always be the best choice, depending on your sample size and
frequency table. In the best case, AIC, CAIC and BIC values agree as to the

Hello r-list members,
I've been doing some linear modeling with a dataset structured as follows.
Tubes containing 500 larvae of Trichinella each were treated with one of
four different temperatures. Each day (or every 10 days depending on
treatment group), 3 tubes were selected from each treatmen

You can add any text or numbers to any place of a graph with this
command:
text(45,20,"some text")
where: 45 is position on the X-axis and 20 - on the Y. Note that numbers

For this type of graph, I would use the functions in the HH package

Hello,
I am doing a confirmatory factor analysis with package Lavaan.
My model consists of 5 factors and I would like to calculate the
factor-reliability and the average variance extracted (AVE) for every factor.
What function can I use to receive this measures? The Lavaan Package doesn't
have
Gregory: Would setting limit.list <- NULL at the start do the trick? See
example below:
Analogue of your example:
lower <- 0
upper <- 0
limit.list<-data.frame(lower,upper)
for(i in 1:12) {
some.data <- rnorm(2)
lower <- min(some.data)
upper <- max(some.data)
one.month <- data.frame(low
I am trying to create a routine that would take a time series and
generate monthly 25%tile and 75%tile limits based on 12 calendar months.
I have succeeded to create a do loop to do this, but can't figure out
how to initiate the receiving datafile (in this case "limit.list")
without sticking an ini
Dear Daniel,
the BIC can be used to estimate the number of classes. This is actually
given out by lca, so you could run lca with several different k and pick
the solution that gives you the best BIC.
Unfortunately I can't tell you whether "large is good" or "small is good"
for the BIC implemen
