lov {lsbclust}

List-of-values Data Set

Description

This is the list-of-values data set used in Van Rosmalen, Van Herk & Groenen (2010). Column names and factor labels differ slightly from that paper. Missing values are encoded as NA as usual. The first nine columns are items answered on a nine-point rating scale, with rating 1 representing 'very important' and category 9 'not important at all'. The respondents were asked how important each of these items are as a guiding principle in their lives.

Examples

data("lov")

## Construct array
lovarr <- indarr(lov[, 1:9], maxcat = 9)

## Run analysis
set.seed(13841)
fit <- lsbclust(data = lovarr, margin = 3, delta = c(0, 1, 0, 0), nclust = c(NA, 11, NA, 5), 
                 fixed = "rows", nstart = 1, iter.max = 50, nstart.kmeans = 10)
