Re-Scaling variables

Discuss the jamovi platform, possible improvements, etc.

I have created a new variable based on a Factor Analysis. How do I re-scale this variable (or a new variable based on this) to 1-100? Is there an easy way? Currently its -x to + x.

Also, will we get a new feature which allows the user to automatically add the factors from a factor analysis as a new variable?

Cheers

Hi, @ scro1461.

Here's a tip for you to scale your variable to 1-100.
Compute a new variable (DATA-> Compute) and insert the formula:
99 / (VMAX (varname) - VMIN (varname)) * (varname - VMIN (varname)) + 1

In the formula, replace varname with the name of your variable to be scaled, while 99 is the difference between the maximum and minimum value of the new variable (100 - 1) and 1 is the minimum value for the new variable.

Cheers,
Maurizio

hi,

this may land by feb, but also might not sorry. i'd say it's 50/50

predicting how long a feature will take to develop is a bit of a black art.
