RE: Lavaan error

[roger akanji]

Hi

I am trying to conduct path analysis using lavaan

Model specification 

specmod <- "
return_on_assets ~ C*equity_based_compensation
derivative_use ~ a*equity_based_compensation
return_on_assests ~ b*derivative_use
ab := a*b
"

Fit model:

fitmod <- sem(specmod,data=df)

fitmod <- sem(specmod,data=Df)

fitmod <- sem(specmod,data=DF)

when i run this model, lavaan error pops up as follows: 

Error in lavaan::lavaan(model = specmod, data = df, int.ov.free = TRUE,  : 
  lavaan ERROR: missing observed variables in dataset: ROA Derivativeuse

Error in lavaan::lavaan(model = specmod, data = DF, int.ov.free = TRUE,  : 
  lavaan ERROR: missing observed variables in dataset: ROA Derivativeuse
Error in lavaan::lavaan(model = specmod, data = Df, int.ov.free = TRUE,  : 
  lavaan ERROR: missing observed variables in dataset: ROA Derivativeuse

Error in sem(specmod, data = df, data = DF, data = Df) : 
  formal argument "data" matched by multiple actual arguments

I am stuck and can't go ahead with my research, can someone help?

thank you very much

Roger

Hi,

 

I would recommend restarting R or clearing the environment to ensure that “specmod” contains the model of interest and not an older version. The code that you profided cannot produce the error that you provided because the model does not have ROA as variable.

 

As a sidenote: I would probably not use lavaan to run the model that you have. The model is saturated path model and just running it as two regressions (lm) gives you the same result with less complexity.

Hi Mikko

Sorry, what you mean by 'The model is a saturated path model and just running it as two regressions (lm) gives you the same result with less complexity'.

do you mean there is another package which works exactly like lavaan? If so, which package do you recommend?

regards

Hi 

Good morning/afternoon

I hope this email finds you well

I am a research student new to mediation analysis. 

I have been following videos on mediation analysis on youtube for some time now.  

I have adapted the model specification used by specialists in youtube videos which seems to me to be ok.

However, when I try to fit model, lavaan error pop up as indicated below:

Error in lavaan::lavaan(model = specmod, data = newdata, int.ov.free = TRUE, : lavaan ERROR: missing observed variables in dataset: return_on_assets derivative_use

Model specification is: specmod <- " return_on_assets ~ c*equity_based_compensation derivative_use ~ a*equity_based_compensation return_on_assets ~ b*derivative_use ab := a*b " Fit Model is: fitmod <- sem(specmod,data=newdata) More so, when I typed in cat(specmod) it gives me the output below: variables X2022 X2021 X2020 X2019 1 equity_based_compensation 0 240588 299517 112206 2

Hi,

 

cat(specmod) should print the model, not the data. But looking at the printout of your data, the variable names are

 

variables        X2022        X2021        X2020        X2019           X2018

This means that your data are in an incorrect format and you need to reshape or pivot the data.

 

https://r4ds.hadley.nz/data-tidy.html#sec-pivoting

 

That being said, I strongly recommend starting with just a set of two regressions (lm command) to estimate your model. Once you have that working, you can move to more advanced analyses.  

 

Mikko
