I need to refresh my memory on Probability Theory, especially on conditional probability. In particular, I want to solve the following two problems. Can somebody point me some good books on Probability Theory? Thank you! 1. Z=X+Y, where X and Y are independent random variables and their distributions are known. Now, I want to compute E(X | Z = z). 2.Suppose that I have $I \times J$ random number

I thought I would write a lottery number generator since I have not had any luck winning the big jackpot - http://megamillions.com/. So far, after over 1.2 million tries, I still have not hit all the numbers from yesterday: 2, 17, 22, 32, 51, 35 (last one is the mega ball). Fun little project that and I thought others would be interested. Let me know if you have a cleaner implementation in mind.

Hi, I''m working on an app - my first Rails - and am looking for some suggestions on the best way (or good way) to set up my models / DB. In general there are teams and matches; a team will participate in multiple matches, and in each match there will be 6 teams - 3 vs. 3. I''m going to want to be able, for a particular team, pull up all matches for that team, to display a

Hi! I'm taking a course that requires some programming background, but I'm a complete novice in the field. when asked to generate a list of 20 uniform random numbers, is it alright if I put in >randu, and just copy-paste the first 20 numbers?? Or is there, as I suspect, a better way of calling out exactly 20 uniform random numbers?? I'm also unable to solve the following problem:

Dear list, I have a question about the interaction between R code and Latex language trough the Sweave function in the package "utils". What I'm trying to do is to write a report. Contrary to the examples shown in the Sweave Manual in which table already constructed by R are "exported" on Latex files, what I would like to do is to build a table in which I combine text and

Hi, I am using lm() for regression analysis of my data set. My regression results look pretty good, i.e., the coefficient is significant and the p value is much less than 0.05. But when I checked the residuals, both using qqnorm() and hist(), the distribution does not look normal. It looks like the residuals have long tails. I assume that lm() uses OLS, and since one of the assumptions of OLS is

I have a dependent variable with is very peaked and has heavy tails, something I haven't encountered before. (histogram: http://postimage.org/image/2sw9bn8pw/). What could be an appropriate family or transformation to do regress on this?-- View this message in context: http://r.789695.n4.nabble.com/regressing-on-variable-with-heavy-tails-tp3486973p3486973.html Sent from the R help mailing list

Hello, I want to fit a distribution to a dataset. Important is not the "overall" fitting but the fitting in the tail (e.g. all observations > x or the n highest values). Standard ML-estimation sometimes doesn't work here very well. We see that especially when we have truncated datasets the algorithms won't converge. In the case of lognormal distribution: It seems that the

Dear R people The function below should be decreasing, convex, and tend to zero when x tends to infinity. curve((1-pnorm(x))/dnorm(x),from=0, to=9) >From the plot we see that for x between 8.0 and 8.3 the function is fluctuating. As far as I understand, this is due to the function pnorm() not being sufficiently accurate in the tails. I am using pnorm() in a way that has probably not been

Hi Shao - looks like forgot to reply to this earlier post of yours, so here goes. On 2016.03.08 04:59, Shao Miller via Syslinux wrote: > 1.

hi all. perhaps someone can help me with subsetting here............ i'm trying to use the nested() function in the bipartite package. my problem is that i have a list of 10,000 matrices and i want the output to be a vector of the nested() function on each of the 10,000 matrices (so i can use these numbers in a statistical test). here is what i'm working with currently: #to store

Here are some thoughts: 1. Customized Syslinux could be customized such that it refuses to boot from USB. No amount of version-matching nor downloading from the same source can help with that scenario. A different Syslinux would be needed, by definition (of the customizer) 2. Slightly less bad is where an ISO or CD/DVD is made with a key piece of non-ISOLINUX Syslinux missing

Hi again, The man page for 'as.matrix' says: 'as.matrix' is a generic function. The method for data frames will convert any non-numeric/complex column into a character vector using 'format' and so return a character matrix, except that all-logical data frames will be coerced to a logical matrix. It's true that "all-logical data frames will

Hi, I''m using backgroundrb 0.2.1 in a production environment and for most parts I''m very happy. We are using it to do some heavy video editing on the server side and it works great except that under, what seems heavy load the below problem happens intermittently. The problem has only happened 5 times out of over 500 runs by our backgroundrb worker. This is the code in our
