Estimate a Latent Class Tree model with Latent GOLD 5.1
1 2 3 4 5 |
Dataset |
A dataframe with the data or the filepath of the data. |
LG |
Filepath of the Latent GOLD executable |
LGS |
Filepath of Latent GOLD syntax for a model with 1- and 2-class splits |
itemNames |
The names of the indicators. If this is not given, all column names of the datafile will be used. |
mLevels |
A character vector being either "ordinal" or "continuous" to indicate the measurement level of each variable. It is required when LGS is specified. |
weight |
Name of the variable with the weights. When all records are unique observations, this should be one for every observation. |
resultsName |
Name of a folder which will be created in the working directory and contains all results by Latent GOLD. |
maxClassSplit1 |
Maximum size of the first split of the tree. Will be assessed with the criterion given in stopCriterium. Defaults to two. |
maxClassSplit2 |
Maximum size of each split after the first split of the tree. Defaults to two. |
decreasing |
Whether the ordering of classes should be decreasing or not. Defaults to TRUE. |
stopCriterium |
Criterium to decide on a split. Can be "LL" (logLikelihood), "AIC" or "BIC". |
minSampleSize |
Minimum sample size of a class. If this is below 1, a probability of the total sample size is used. |
nKeepVariables |
Number of variables to be kept if one wants to explore the results with external variables. |
namesKeepVariables |
Number of variables to be kept if one wants to explore the results with external variables. |
sets |
Name of the variable with the weights. When all records are unique observations, this should be one for every observation. |
iterations |
A character vector being either ordinal or continuous to indicate the measurement level of each variable. It is required when LGS is specified. |
The LCT
function constructs a LCT model by sequentially estimating 2-class models with Latent GOLD 5.1.
This can be done automatically for standard models, but for more complex models a customized Latent GOLD syntax can be provided.
The model size of the root can be increased with maxClassSplit1
and the remaining splits with maxClassSplit2
.
Results of a Latent Class Tree analysis in an object of class 'LCT'
, which is a named list with two named lists.
The first list contains information on the setup of the tree and the second list contains information on every split.
