save factor scores, regressions residuals, etc. ?

Post by ftr »

Hi,

I just start de discover jamovi and it looks promising. Thanks for the work.

I search how to save for instance factor scores, regression residuals, etc. In survey research which I do, for short, you have a given problem and you operationalise it into questionnaire items. For the analysis you have to reverse the process and bundle the respondents' answers again. Which you might do with a principal component analysis, for instance. And then you use the dimensions again in other procedures (or programmes).

So, my question is: can you save factor scores, regression residuals by case ?
If this is not implemented is there a planning to do so ?

Thanks in advnce,

hi,

at the moment, there's no way for an analysis to 'generate' data. i.e. to populate a column in the data set with, say, residuals.

but this is something we're keen to add, hopefully in the next 6 months.

kind regards

As soon as possible will be the best to give jamovi a good ranking among other packages. The job that has be done is very nice. Congratulations

Hi,

Please could we have an update on this? I too am looking for the ability to save component scores from a PCA, as well as standardised residuals.

Best wishes,

hey,

sorry, no real progress here. but thanks for bringing it up.

you're right, it is a "must have" feature.

Hi,
It would be helpful to have an approximate date for the update that will integrate the "must have" feature.

What do other user say about it ?

oh yup. perhaps fill us in on your need here. do you want to use it in a course, beginning X? (for example).

Hi jonathon,

For our course of multivariate statistics with about 250 students we would also be really thankful if you implemented this feature for summer 2019. We missed that feature this semester ;-)
We will also think about some other features missing for our objectives (e.g. the possibility of setting orthogonal factors in CFAs), maybe I will be able to contribute too.

Best regards and good job again,
Folax

thanks folax,

although, you need to be careful referencing seasons when corresponding with residents of oceania :)
