[R] Division of data set with some restriction

Dear Group members Can any one help to code this situation. Suppose we have a population with some mean and a standard deviation. Then , there are n1 observations out of n which are less than or equal to n. Also, there are n2 observations out of n which are greater than . We divide the

Two concerns with implementing this philosophy. 1. Determining whether a question is indeed seeking an answer to a homework exercise. Certainly if I think a question is short-cutting a basic homework task I ignore it. But I don't waste an email berating the alleged student. 2.

I'm glad to see the issue of negative feedback addressed. I can especially relate to the 'cringe' feeling when reading some authoritarian backhand to a new user. We do see a number of obviously inappropriate or overly lazy postings, but I encounter far more postings where I don't feel competent

Sorry, poor phrasing on my part; on the occasions where someone is rude, all I see is... I agree the public cautioning should be done by moderators, yes. On 25 January 2016 at 16:13, Duncan Murdoch wrote: > On 25/01/2016 3:33 PM, Hasan Diwan wrote: >> >> There exists a

Do you have the sample sizes that the sample proportions were computed from (e.g. 0.5 could be 1 out of 2 or 100 out of 200)? If you do then you can specify the model with the proportions as the y variable and the corresponding sample sizes as the weights argument to glm. If you only have

I think this would be re-defining the role of the moderators for list, which is essentially to filter out spam. Only new members are subject to this moderation, and if a message is genuine then their moderator flag is cleared (i.e., they are no longer subject to moderation). Thus the list

Hi Muhammad, There are a large number of approximate answers to your problem. One easy one is to ensure that the standard deviations of the subgroups are maximally different by dividing the observations into "mids" (observations close to the mean) and "tails" (observations far from the mean). The

I'm finding it very difficult to figure out how to read the value of "celltag" for a given cell in a tktable. I'm sure it's something like: tcl(classTable, "get", "celltag", row, column) but of the dozens of variations of names, options, args, and formats I've tried, nothing is working. Any
