Re: [R] dependent p.values in R

could simply average those p,values but to my knowledge that approach is biased so i thought, in the same way there is a method to combine independent pvalues (e.g. stouffer method); is there a way to combine dependent pvalues? best f Fernando Marmolejo-Ramos

dear R users is it appropriate to use a Log likelihood ratio (G-test) test of independence when dealing with repeated categorical responses (e.g. 2 by 2 table) instead of the McNemar test? thanks fer [[alternative HTML version deleted]] __

[R] calculating the mode in R...

Dear R users I’m aware that the package “modest” is useful to find the mode in an array. However, I’d like to know if someone has translated the “mode” function built-in in MATLAB into R language. This function finds the most frequent value in an array

[R] simulating Likert-type data

Dear R members Could someone indicate me how to simulate Likert-type data using the GAMLSS library and how to fit that data? Let’s say, 50 random numbers in a variable that goes from -4 to +4 in steps of 1 (i.e., -4, -3, -2, -1, 0, 1, 2, 3, 4) with a mean of 2 and SD of 0.15 and belonging to a

[R] transformation and outliers

Dear R people I ask again… 1. Is there a published reference presenting the normal score transformation? Is there a published paper (in any field) using that transformation in the analysis of data? And this is a new question… 2. The “outliers” library has a function called

[R] normal score transformation...

Dear R members I’m interested in reviewing some data transformations. I’ve found literature regarding Box-Cox, logarithmic and square-root transformations. I know there is a library called “coin” which contains a transformation called normal score transformation (see “normal_trafo” function).

Dear R team Jim Lemon recently said regarding new improvements in PrettyR and plotrix: “Remember, it is your whingeing and moaning that have helped to make these packages what they are today.” So, this is my whinge: out there is a freeware called Vista, which runs, among other things, bootstrap

Re: [R] Interpretation of t.test results

Dear Omar Your t.test is telling that the 2 groups are not different. Now it is not clear if you want to compute the CI for the difference or for each group. If the former, then the outputs provides you with that information. It’d be clearer if you provide the full syntax of your t.test. For
