You should be able to pick up a guidebook for your model here.
I'm not quite sure if this is the right place to post this, I'm in a math class where everyone is using the model below and the teacher isn't able to help me. I'm using a TI-89 Titanium.
Logarithmic Transformations, where you are given two sets of data (independent and dependent), put them into the stat/list editor, then use the LinReg(a+bx) to find the regression line and residuals. I'm fine up to here, but I'm stuck where I then have to transform the data into a 'straight' line using log10y ect.
I'm at my wit's end, any help would be wonderful.
