My question is, are my diagnostic tests concidered unpaired or paired?

Cheers ]]>

In my study I had two groups of people (depressed patient vs. healthy control) and I compared their neural physiologic activity (EEG power), cognitive ability (TMT task), and total physical activity. Afterwards, I wanted to see how well these dependent variables could assign which group (patient, control) the subjects belong to.

So here comes the questions, I have only EEG power and cognitive ability data are normally distributed but not the physical activity. Should I then use non-parametric test for all DVs? Or should I mix the independent sample t-test and say, Mann-Whitney test according to the normal distribution outcome?

Also, when i want to do the categorisation, that would be either linear discriminant analysis or logistic regression and I can opt for. I'm aware that normally distribution of IVs is one of the prerequisites for using LDA, but in my case some IVs are but some aren't. Should I then consider LR or should I run the test separately?

Is there any better way to deal with mixture of normally distributed DVs and IVs?

Thanks in advance. ]]>

The above page describes how the top 250 is calculated where the m (prior) value is set at 25000 for top 250, and for bottom 100 , the m value is set at 1500.

My question is the following

1)Why conduct bottom 100 separately because the bottom 100 can be obtained after obtaining the Bayesian scores for the entire data set of movies while obtaining top 250 ?

The following website uses a only a single formula with m=13.

A example would help.

Lets assume the following case

I have 50 movies in the database. I need to calculate the top 5 and bottom 5.

I set the m value at 200 ( based on the finding that 70 percent of the movies i,e 70% of 50 = 36 movies have ratings above 200)

I now calculate the Bayesian scores for all the 50 movies

and obtain the top 5 and bottom 5 from from the rankings obtained for those 50 movies.

The above method is pretty much the way it should be done and is done by the anime website. Does it validate the question that i asked about imdb ? ]]>
