This function simplifies the specification of latent class models: models that estimate membership of a categorical latent variable based on binary or ordinal indicators.

`mx_lca(data = NULL, classes = 1L, run = TRUE, ...)`

- data
The data.frame to be used for model fitting.

- classes
A vector of integers, indicating which class solutions to generate. Defaults to 1L. E.g.,

`classes = 1:6`

,- run
Logical, whether or not to run the model. If

`run = TRUE`

, the function calls`mxTryHardOrdinal`

.- ...
Additional arguments, passed to functions.

Returns an `mxModel`

.

```
if (FALSE) {
df <- data_mix_ordinal
df[1:4] <- lapply(df, ordered)
mx_lca(data = df,
classes = 2) -> res
}
```
