Hello

I am using survey data, complex design survey called HRS data. I wan use linear regression but need help someone to look at my outcome after I did the log transformation with my main predictor. I have attached the pdf

Do you have repeated data of some kind? Did you standardize your predictors?

why would I need to standardize my predictors ? do you mean adjust for them ?

Sorry, standardize your independent variables

sorry still I don't get that, why I need to standardize my independent variable? I am not looking at interaction here. to what I know is that I only standardize my independent variable in cease I want look at the interaction.
can you explain how I standardize it ?

Why standardize your independent?

What happens if one variable is in the 10,000 range and one is around 10?

The biggest concern that popped up for me is that all the predictions are around 2. The range seems very very narrow.

Hi dode,

Welcome to the community! I understand that it may be easier to directly communicate about your scenario, but I encourage you to think it through here on the public community so everyone can benefit. Other members may have similar questions, and will be interested in how you work it out.

All the best,

Anna

Not unless you're paying me, and my consulting rates start at $100/hour 🙂

Otherwise, all discussions need to remain on here.

so dose that mean, I should not use linear regression in this case?

You're not asking for programming help here, you're asking for statistical advice/methodology. There's a little less of that on this forum and I'm probably not the best person to answer anyways.

I've moved your question (and edited the title to correct for spelling mistakes) to the Statistical Procedures forum which is more appropriate.

I would also suggest you review the assumptions for linear regression and determine if it's appropriate for your data. You can also post this on Cross Validated, which is specifically designed for these types of question, but make sure to elaborate your question, including your hypothesis and context of the question may help. Otherwise you're likely to have your question down-voted and rejected.
