This video put me on a different path of thinking about the data and data modeling. Thank you,

Thanks sooooo much! I was able to complete my assignment using this thorough and descriptive video.

Thank you Dr. Grande! That helps a lot for my midterm!

Thank you very much. This is very easy to understand

Thank you. Your videos are very helpful and well-explained.

Thank you Dr.!

Thank you! You're the youtube God of SPSS!

Thanks, Dr.

Hi Dr Grande,Thanks for de vid. I Have some questions about curvelineair multiple regressoin. What are the implications if only the quadratic term of the variable is significant? Does this mean that there is a curve in de best fitting line, but no change in direction ( I asume if the beta value of the predictior is posititive for the linear term and negative for the quadratic term of the predictor de bend in the line changes also of directon). My second question is. Can I use the options "backward" or "forward", because I have a lot of predictors in my model, and so spss runs automatic to a model that fits the data best. Thanks for reply

Hi, Dr Grande Do we need to transform only the predictor variable or both. Thank you.

is there a way to find the max and min values for this function? for example, I'm trying to model a dose-response relationship and trying to find the threshold at which the slope of the function changes from positive to zero and then negative. How do i find this point? My thought is taking the second derivative for max/min, but is there a way to do it within spss?

Hi Dr. Grande, can you make a video on using syntax for curvilinear regression?

Quick question: what does it mean when the 'sig if change' of model 2 is not significant, but its ANOVA is? Is it that the model is significant?

Thank you for the video. How to do the Curvilinear Regression Analysis at different levels of moderators i.e. +1SD and -1SD

How would I do this if I want to test an inverted U shape relationship?

I just wondering, actually i'm new to this kind thing. 1) Is there any way to show the value not in R square but R? Some (and if im not mistaken, most) scientific paper show correlation of two variables with R value... 2) and which better to represent correlation, R or R square? Thank you for your help

Wasn’t you just take the square root of the r2?

Good morning doctor Todd Please, can you make a video on: How to read, interpret and write the results (output tables) of non-linear regression?? Thank you Best regards Doctor Sameer

Can i remove constants... Because pvalue is greater than 0.01

How to interpret the results of nonlinear regression in SPSS?

Thank you.
