Hello What is the difference between ordered and unordered solutions for a Latent class analysis with categorical variables? |
|
|
I don't know about that term. Unordered usually refers to a nominal variable, as opposed to an ordinal variable. |

|
Thank you. I am getting an error of this *** WARNING in ANALYSIS command Estimator WLSMV is not allowed with TYPE=MIXTURE. Default will be used. 1 WARNING(S) FOUND IN THE INPUT INSTRUCTIONS What would be the change of TYPE to? |
|
|
Mixture requires Estimator = ML(R). |
|
|
Thank you. What type would work with WLSMV? |
|
|
General single-level and multilevel. |

I have a data set that I am examining 9 variables that I am attempting to perform an LCA: 1 coded as binary 6 coded as ordinal with 3 levels each 2 coded with as ordinal with 4 levels each Would this all be considered a categorical LCA? |
|
|
Yes. |
|
|
This has been very helpful. which type command and which estimator would you recommend using based on the variable description I have provided? |
|
|
How are we able to view class membership in the output? Is there a Tech command that should be used? For example, how would I determine this information? Mplus creates an output file which contains the original data used in the analysis (i.e., item1 to item9) followed by the probability that Mplus estimates that the observation belongs to Class 1, Class2, and Class 3. Next, the class with the highest probability (the modal class) is shown. |

Use ML. See the video and handout from our Short Course Topic 5. |

Hello I am performing a LCA and I want to use the DEFINE command to sum the number of criteria met for my various classes. In the topic 5 video it stated that this can be done. I was getting an error and am not sure if I am writing it correctly. Data: FILE IS /Users/wfmcbr01/Desktop/Dissertation/Dissertation Work/dissertation_LCA_1156.csv; Variable: NAMES are wmt_lca msvt_lca nvms_lca rds_lca f_lca fp_lca fs_lca fbs_lca rbs_lca; CLASSES = c (4); CATEGORICAL = wmt_lca msvt_lca nvms_lca rds_lca f_lca fp_lca fs_lca fbs_lca rbs_lca; DEFINE: SUM = Sum (wmt_lca msvt_lca nvms_lca rds_lca f_lca fp_lca fs_lca fbs_lca rbs_lca); Analysis: TYPE = MIXTURE; For some reason it is not working properly. Thank you, |

Use Savedata to save CPROBS. Then look for the column with Most Likely Class. Then for each class, sum up the criteria. |
