1. The effect of a single continuous IV on within subjects change

Could someone please suggest the most appropriate method of analysis to examine the effect of a continuous IV on a within subject (repeated measures) DV with 2 levels (pre-post)? I have a leadership intervention where we measured "leadership style" (DV) before the program and again after the...
2. Change variable PDF with less variables than before

My question is very simple, I have a probability density function that depends on four variables p(x1,x2,x3,x4). Now each of those variables depend on three new variables, i.e xi=xi(y1,y2,y3) so I want to find the new PDF given by p(y1,y2,y3). The problem is that the jacobian of this...
3. Change within groups and differences between groups

Hi All, I have a question that perhaps is basic for most of you. I am hoping I can rely on your expertise to answer this question. I am trying to study the effectiveness of an intervention. All participants receive the intervention. Upon analyzing the demographics of the participants I...

Hey all! This is a question about methods. I am really noob but want to learn. If you have a book or papers to suggest that is helpful to! How can you model change over time? Dependent variable: Interest Rate 1980(IR80), Interest Rate 2000(IR00). I have these for many institutions. Can a new...
5. Help! Looking for appropriate analysis for 2 points data set

Title is pretty forward... I know I could use an ANOVA in theory, since I am looking at the change of my DV caused by an IV. The only thing that makes me unsure of what is the appropriate analysis is that I actually want to see if the change in my IV affects the change in my DV. For...
6. Standard deviation of the mean difference out of Pre/Post Test Descriptive Statistics

I have several RCT pre/post intervention studies that I am calculating Hedge's g for. All of the studies report the difference of mean and difference of standard deviation between pre/post for each group except one. I know how to calculate the difference of mean [= Mean(post)-Mean(pre)], but...
7. change sign estimate manually because of underlying theory

*****the thread should be: change sign observations variablebecause of underlying theory****** (sorry for the mistakes in the previous version of this post) Dear forum readers, Is someone allowed to put a minus in front of a variable observation, to obtain its contrary, if this is supported by...
