...es directly, isn't it? (2) I often have to use the "fitdistr" function included in library MASS. The generated output for e.g. $estimate has the following format: mean sd 0.01664940 0.97682797 Now I want to write ONLY THE VALUE in a new variable. By doing mean_a = ...$estimate[1] I always have the string "mean" IN the variable. How can I eliminate this? Thanks a lot for your answer ! Carsten

dear experts, I reproduced an experiment (questionnaire) some times. The result of the experiment is a vector of 5 factors, say (A,B,C,D,E). In the original article the result is given in 5 pairs of mean and stDev for A .. E, e.g. mean_A=37.4 and sd_A=8.1. The interval for A,B,C,D,E values is 0..50. The original data frame is not available. For a comparison of my results L=(A',B',C',D',E') with the original G=(A,B,C,D,E) we can interpret that smaller sd-values are 'better'. But for the means the inter...

Hello. How can I compute the Bootstrap p-Value for a one- and two sided test, when I have a bootstrap sample of a statistic of 1000 for example? My hypothesis are for example: 1. Two-Sided: H0: mean=0 vs. H1: mean!=0 2. One Sided: H0: mean>=0 vs. H1: mean<0 I hope you can help me Thanks in advance Regards, Andreas
