    Effect size in regression

    Hi Noetsi, thanks for your reply. I have a doubt on your (and Hlsmith) comment: You both coincide when suggesting that the authors of this report might be trying to standardize the slope coefficient. However: 1) if that would be the goal, would it not be achieved when dividing by the standard...

    Effect size in regression

    Hi hlsmith, Thanks for your answer. Unfortunately, the methods section is very short and table/ figure legends do not provide further details. Let's see if anyone else has seen this procedure before and can provide further details. In any case, your answer is very much appreciated

    Effect size in regression

    Hi everyone, I am reading an article at which authors used an effect size that it's totally new to me and I do not know how to interpret it. I would appreciate if anyone could explain its meaning or provide any reference about its interpretation. Below, I paste some sentences from the original...

    Local association measures

    Hi everyone, I have read that there are local measures of association to be used when wanting to conduct a finer-grain analysis of an X-Y association (Grissom and Kim, pages 101-102). However, this comment is framed in the context of two continuous variables and I wondered whether these local...

    Percentages and statistical significance

    Hi Sh7, I am not a stats expert but, perhaps, my comments would be useful to you. If I understood properly, you want to compare two proportions (you do not need to transform them to %): The proportion of false memories in the condition "distractor" and the proportion of false memories in the...

    effect size

    Hi Moyu, Interpretation of effect size is always context-dependent. In clinical contexts, even small effects might be important. This is easy to understand if the treatment being tested is actually saving lives (i.e. only one 1% more of efficacy could save the life for thousands of people!) If...

    How to summarize a pattern of correlations?

    Hi, I have performed a small memory study at which participants could commit two types of errors (false positives and false negatives; F+ and F-) in four different stimuli categories. I have observed that the two kinds of errors (F+ and F-) for two stimuli categories show a reciprocal pattern...

    reporting chi-square in 2x3 contingency table

    Hi Karabiner, thanks a lot for your reply. I am happy to be corrected when I still have the opportunity to do things properly. However, if I may, I would like to ask for a little bit more help here. I assume that I should just calculate means of A, B, C and then compare them by a MANOVA... would...

    reporting chi-square in 2x3 contingency table

    Hi everyone, I am conducting an experiment and I have two groups of participants (controls/ treated; 50 each). For each participant, I performed 40 measures with 3 possible outcomes (A, B, C) and recorded the accumulated frequencies (for example: control1: 10A, 20B, 10C; Control 2: 20A, 10B...

    how to automatically repeat the same analysis

    Hi obh, I am using chrome and what I did was break down my analysis to batches of 50 dependent variables at the time. It worked nicely and it repeating the process four times was 50 times better than having to eat 200 times ;) Of course, this kind of analyses should be handled with powerful...

    how to automatically repeat the same analysis

    Hi obh, thanks a lot. I am not sure if I explained myself right. So, I attach an snapshot from SPSS output and indicate there what I meant about standardized coefficients. Seems I am using SPSS in Spanish, I added some labels by hand. One more time, thanks for all your help and patience. :-)

    how to automatically repeat the same analysis

    Hi Obh, First of all, let me thank you for your patience and continued help. I now got the residuals table I was looking for. I have also obtained the regression coefficients, although only the unstandardized ones. It would be great to also obtain the standardized ones to have a first grasp of...

    how to automatically repeat the same analysis

    Hi obh, Thanks for your new response. I would like to obtain the residual values but I did not see how to do that. I would also like to obtain standardized regression coefficients... Perhaps I am doing something wrong but I do not see any option named "cached images and files" but I obtain the...

    how to automatically repeat the same analysis

    Hi Obh, Thanks a lot for your fast answer and for providing this link. It does not entirely respond to I need now but I am sure it will be useful in the future. I have checked this resource and it seems to work properly (at least with 25 dependent variables, I have only tried with a subset...

    how to automatically repeat the same analysis

    Hi everyone, I am conducting a study and I have to perform over 200 multiple regression analyses with the same predictors (2, one dichotomic and one continuous) but with different dependent variables. Of course, this might just be done manually, but it might be too time-consuming and prone to...

    What post-hoc test to use with 2x2 repeat measures ANOVA

    I am not a stats expert but I will give my opinion that I hope it might be useful (and, hopefully, confirmed by someone with more knowledge). since you do only have 4 comparisons, type I error is not a major concern and you could use almost any posthoc (although I would not recommend using LSD...
