Hello, I am running some latent transition analysis and would like to further analyze the latent classes by subject number. However, every time I run SAVEDATA: File is ltams.txt; SAVE = cprobabilities; I get *** WARNING in Savedata command (Err#: 9) Error opening data save file: ltams.txt Data will not be saved. Any suggestions? Thanks |

You either have a path that is not correct or you don't have privileges to open the file. If you can't figure it out, please send the problem and your license number to support@statmodel.com. |

Thank you. I figured it out. Stephanie |

Hi! Using the following command "SAVE IS CPROB" I got a new data set. How can I get a new data set with the id variable? Thanks in advance, |
|
|
Use the IDVARIABLE option of the VARIABLE command. |

Thanks Linda, I am generating new data set which include the original id varialbe. Below is the syntax I typied. data: file is "C:\data\this.csv"; variable: NAMES ARE ID sc2-sc6; USEVARIABLES ARE id sc2-sc6; IDVARIABLE IS id; classes = c (3); ANALYSIS: TYPE = MIXTURE; model: %overall% i s | sc2@0 sc3@1 sc4@2 sc5@3 sc6@4; OUTPUT: tech1 tech8 tech11 tech14; SAVEDATA: file is "C:\data\new.sav"; SAVE IS CPROB; How can I get new data which include the origianl id variable? Thanks, |

It should with what you show. Please send the full output and your license number to support@statmodel.com. |

Hello, I'm trying to save model-predicted values in a growth curve model. The user guide explains how to save factor scores, but not how to do it for simpler growth models and I was unable to find a solution on the forums. Is this possible in the current version of Mplus? Reviewers have requested we calculate the reliable change index and due to missing data, I've assumed that using predicted values would be the best route. Am I missing a better alternative? Thanks very much. Matt |
|
|
You would need to create these model-predicted values in the DEFINE command and save them. |

Dear Professor, How can I save class probabilities and most likely class membership for each simulated data set? Thanks! |
|
|
Use the CPROBABILITIES option of the SAVEDATA command. |

Thank you, Professor! But if I simulated 100 sets of data, can I obtain class probabilities and most likely class membership for all these runs using some functions in MPlus? I hope my question makes sense. Thanks! |

Dear Professor, as per my last question, I'm pasting the codes: Title: New data sets to be saved data: FILE IS simlist.dat; !a file that contains a list of names of the generated data Type = Montecarlo; variable: names are y1-y4 x1 x2 c0; USEVARIABLES ARE y1-y4; classes = c(2); Auxiliary = x1 x2; analysis: Type = mixture; model: %overall% i s | y1@0 y2@1 y3@2 y4@3; i* s*; i with s*; y1-y4*(ve); [c#1*0]; %c#1% [i*]; [s*]; %c#2% [i*]; [s*]; Output:Tech9; savedata: FILE IS simp.dat; save = cprobabilities; The codes ran very well except that I got the following warnings and so I couldn't save the new data sets. May I know how can I get the new data sets? "*** WARNING in SAVEDATA command The FILE option is not available for TYPE=MONTECARLO or TYPE=IMPUTATION. The FILE option will be ignored. *** WARNING in SAVEDATA command The SAVE option is not available for TYPE=MONTECARLO or TYPE=IMPUTATION. The SAVE option will be ignored. 2 WARNING(S) FOUND IN THE INPUT INSTRUCTIONS" Thanks always for your help!!! |

You would need to run each data set separately to save the files you want. |

Hello, I'm running into a problem saving cprobs with an ID variable. Could you please help me figure out the error? The syntax I'm running is: data: file is "C:\data\LSAC.csv"; variable: NAMES ARE ID Sex A1-A5 T1sweight; USEVARIABLES ARE ID A1-A5; IDVARIABLE IS ID; MISSING=all(-999) classes = c(4) cSex(2); knownclass = cSex (Sex=1 Sex=2); weight is T1sweight; analysis: TYPE = MIXTURE; model: %overall% i s q cu| A1@0 A2@1 A3@2 A4@3 A5@4; i@0; s@0; q@0; cu@0; OUTPUT: tech1 tech8 tech11 tech14; SAVEDATA: file is "C:\data\new.csv"; SAVE IS CPROB; If I run it without "IDVARIABLE IS ID;" and remove ID from usevariables, it runs fine and saves the cprobs without an ID, but when I include the line it says: *** ERROR The number of observations is 0. Check your data and format statement. Data file: c:\data\LSAC.csv *** ERROR Invalid symbol in data file: "11103503" at record #: 1, field #: 1 Miri |

Open your data set in the Mplus Editor. You will see the invalid character at the beginning of the data set. Delete it and resave the data. |
|
|
Magic! The invalid character didn't show up in SPSS or Excel, but the MPlus Editor did the trick. Thanks, Linda. All the best, Miri |

Hello, I am attempting to run an LCA analysis in Mplys, v7.4. I have specified the following SAVEDATA command: SAVEDATA: File is C:\Users\Camilla\Desktop\2.0(SMRdata2016)\2classdich.csv; SAVE is cprob; format is FREE; But I get the following error message: *** ERROR in SAVEDATA command The syntax for the FILE option has changed. Please refer to the Mplus User's Guide for available options. I have looked in the manual, but I do not see any changes to the code. Might anyone be able to help me to see what the issue is? Thanks so much, Camilla |

The parentheses in your path are triggering an old Mplus feature. Remove the path or specify a different folder to save the file in. |
|
|
Thuy, Thank you so much! That fixed the issue. I really appreciate your help! Happy Friday, Best, Camilla |

Hi, I am saving factor scores for use in a subsequent analysis as part of a large simulation study. I am finding that my saved data is not the same length as the original data. The input data has N=10400 and the saved data is only of length 10000. Is 10000 the maximum possible length of SAVEDATA file? Is there a way around this default value? I tried RECORDLENGTH IS 10400 but it didn't seem to work. Thank you, Justin |

Forgive my previous post, it appears that the output file states that the record length is 10000, but the actual saved data does include all 10400 records. Thanks! |

Hi, I am running an LCA and that works perfectly. Only when i try to use a 'savedata' command it says "the number of observations is 0. Check your data and format statement'. Mplus also erases the data in the file i used. without the save data command it works perfectly. Any ideas? Title: Latent Class Analysis. Data: File is "LCAvrm1.dat"; Variable: names =ID VLGTK VLGTL rvp pal ots swm; usevariables = VLGTK VLGTL rvp pal ots swm; classes = c(2); Missing is ots (999)VLGTK(999)VLGTL(999); Analysis: Type=mixture; Plot: type is plot3; series is VLGTK (1) VLGTL (2) rvp (3) swm (4) pal (5) ots (6); Savedata: File is "LCAvrm1.dat"; save is cprob; output: tech11 tech14; |

You can't use the same file name in the FILE option in both the DATA command and the SAVEDATA command. Change the name in the SAVEDATA command. |

Hi, I'm running an LPA. I'd like to save cprob as well as an additional variable (erTraM_1), which is not an indicator of the profiles. I need the additional variable in the data file for further analysis. Is this possible in Mplus? Thanks for your help! Julia VARIABLE: NAMES ARE id erTraM_1 sex sskM_1 soFaM_1 svVK4I_1 svCK3_12; IDVARIABLE IS id; USEVARIABLES ARE sex sskM_1 soFaM_1 svVK4I_1; AUXILIARY = svCK3_12; CLASSES = c(3); CATEGORICAL = sex svVK4I_1; Missing = ALL(-999); ANALYSIS: TYPE = MIXTURE; STARTS = 500 50; STITERATIONS = 50; SAVEDATA: FILE = LPA_3-CLASS_Fa.dat; SAVE = CPROB; OUTPUT: ; |
|
|
Use Auxiliary = erTraM_1; |

Thanks for the help! I'm running now the further analysis (see post above) and I have a problem with the dataset, I saved before via sava data-command. Followin gerror message occured: *** ERROR Invalid symbol in data file: "*" at record #: 72, field #: 6 What's the problem here? I thought that "*" is ok as it specify missing values. |
|
|
You need to add MISSING = *; in the VARIABLE command. The saved data set uses * as missing. Be sure you are reading the data set according to the specification shown at the end of the output where the data were saved. |

Hi, If I simulated 100 sets of data, can I obtain class probabilities and most likely class membership for all these runs using some functions in MPlus? Thanks! Is RUNALL utility, in this case, can be helpful? |
|
|
See Mplus using R in the left column of the website. MplusAutomation is probably easier to use than Runall. |

Hi, I was trying to save cprobabilities using: SAVEDATA: file is lpafull.txt save is cprob; My initial run was fine. Then I used the exact same syntax with a large data file (over 100k participants). The saved data file had only my original variables as shown below, no cprob values: SAVEDATA INFORMATION Save file lpafull.txt save is cprob Order and format of variables D1 F10.3 D2 F10.3 D3 F10.3 D4 F10.3 ID1 I7 G I2 Save file format 4F10.3 I7 I2 Save file record length 10000 Can you please let me know what I am doing wrong? thank you, G. |
