1. ### Determining how similar different sets of data are

I hope this is in the right spot: I have a dataset of ~15,000 unique, nominal, categorical members. From that dataset, I have ~3,000 samples that are subsets of the overall dataset. Each sample has 100 unique members. A member's inclusion in a sample/subset is binary: either it is fully...
2. ### Subset regression error?!

So I have 11 predictors and one response variable. I am wanting to look at the relationship (see what predictors effect the variable) and as I can't put all my predictors into multiple regression, I thought subsets would be best. Unfortunately when i enter all my data it comes up with the...
3. ### Comparing frequency distribution between the subsets of the datasets

Hello, I have met some problem with testifying differences between frequencies. Let's me present it with concrete example. 1. I have 100 sample plots in three habitat types: deciduous (DW), coniferous (CW) and mixed (MW) wood. 2. Each of the plots (DW1,..., DW35, CW1,...,CW35, and...
4. ### Normal distribution populations with a subset of the population that is not norm. Dis

Identify an example of a population that you would expect to be normally distributed. Explain why, according to you, it would be normally distributed. Then, describe a subset of the population you identified and explain why it would not be normally distributed and what the distribution would...
5. ### Identifying subset with maximum averages

Dear all, I am trying to achieve the following task - and I wonder if there are analytical methods in any of the stats packages that can achieve it. I have a dataset of 1000 X 500, 1000 value of "song evaluation scores", by 500 cases (persons). I am trying to find a "score-maximizing...
