Comparing google analytics results to one&one hosting monthly statics shows a huge discrepancy. For last month: Google shows 1046 visits. One&one stats show 15304 unique visits. The google code is in the footer which appears on every page. I'm aware ga only works with js enabled but to assume that many non js users??? ...
I have a bunch of measurements over time and I want to plot them in R. Here is a sample of my data. I've got 6 measurements for each of 4 time points: values <- c (1012.0, 1644.9, 837.0, 1200.9, 1652.0, 981.5, 2236.9, 1697.5, 2087.7, 1500.8, 2789.3, 1502.9, 2051.3, 3070.7, 3105.4, 2692.5, 1488.5, 1978.1, 1925.4, 1524.3, ...
I am working with a large amount of time series. These time series are basically network measurements coming every 10 minutes, and some of them are periodic (i.e. the bandwidth), while some other aren't (i.e. the amount of routing traffic). I would like a simple algorithm for doing an online "outlier detection". Basically, I want to kee...
I have to estimate parameters of a mixture distribution which consists of Pareto distribution and Exponential distribution. I am using maximum likelihood estimation procedure by using log likelihood function and differentiating it with respect to each parameter.Since the log likelihood equation is non linear, I have to use Newton Rhapson...
Greetings, I have three TS variables resembling something like the following: data <- read.csv(...) dataA = zoo(data$valueA, data$date) dataB = zoo(data$valueB, data$date) dataC = zoo(data$valueC, data$date) days = seq(start(dataA), end(dataA), "day") dataAts = na.locf(merge(dataA, zoo(,days))) dataBts = na.locf(merge(dataB, zoo(,day...
Hi, Can anyone please tell me what do you mean by process spread in terms of 6 sigma methodolgies. 2)what is Cp and Cpk measurements?I had seen the net but the examples and interpretaions seems to me very vague and unclear Regards Maddy ...
We're currently questioning our company's data model (database schemes), which has grown wildly and distributedly over the years and now suffers from redundancy and lacks clarity. Different databanks (Oracle and MySQL) are queried by different tools, developed by separate teams for different purposes (billing, reporting, business, etc). ...
Hello, I'm new to R and I'm trying to create a .R script that will open up a .csv file of mine and compute some frequencies. There are headers in this file and the values associated with them are either 1,0,NA, or -4. What I want to do is go through each vertical row and then compute the frequencies of them. I'm sure this is an easy scri...
Hi, I'm trying to replicate a linear discriminant analysis output from SPSS in R, and I'm having difficulties to find a way to perform an m-box test. The only thing I found was some code posted in a forum, to manually implement the process, but I was wondering if there is nothing for this purpose already incorporated in the language it...
A client has a site where video content is populated by AJAX from a video CDN. Each link is built like so: <a class="thumb-link" href="/?video='.$video->id.'" onclick="show_video('.$video->id.', \''.$section.'\'); return false;"><img src="'.$thumb.'" width="100" height="65" alt="" align="left" /></a> But they report that analytics is ...
I have a program which records events that occur with some probability p. After I run it I get k events recorded. How can I calculate how many events there were, recorded or not, with some confidence, say 95%? So for example, after getting 13 events recorded I would like to be able to calculate that there were between 13 and 19 events t...
Hello, Is there any framework or way that I can have my mac application report back usage statistics to me? It is programmed in xcode objective c. Thanks! Christian Stewart ...
I'm thinking about writing a little library to make a guess at the name of an (RGB value) colour, from a predetermined list of candidates. My first attempt was based purely on pythagorean distance within the three-dimensional RGB colour space - this wasn't massively succesful as most of the named colour points were at the edges of the s...
I am refactoring a rather large body of code and a sort of esoteric question came to me while pondering where to go on with this. What this code needs in large parts is shortening of subs. As such it would be very advantageous to point some sort of statistics collector at the directory, which would go through all the .pm, .cgi and .pl f...
I have an online image sharing platform based on PHP5 + CodeIgniter. I would like the application to show to the user the number of unique views per image. Users can access image pages anonymous or signed in. Although I know how to implement such a thing myself, I prefer to "outsource" the recording of unique pageviews, for reasons of p...
I'm looking for a built-in function that returns the sample quantile and an estimated confidence interval in something other than MATLAB (MATLAB's ecdf does this). I'm guessing R has this built-in and I just haven't found it yet. If you have any standalone code to do this, you could also point to it here, though I hope to find somethin...
When i look at the source of R Packages, i see the function sweep used quite often. Sometimes it's used when a simpler function would have sufficed (e.g., 'apply'), other times, it's impossible to know exactly what it's is doing without spending a fair amount of time to step through the code block it's in. the fact that i can reproduce ...
I need to find a list of commonly mistyped keys on a keyboard for a project I am working on. Basically I need to know what key a user is trying to press and what key they are actually pressing and a comparative measure of how often this happens. By "comparative measure" I mean that I would like to be able to say that knowing a user m...
Is there some way to store: A visitor's IP Address What time a visitor visited my site How many times they visited I know there is a way to do this without PHP, just with Javascript and some text files. Edit 1: How it would I do this in PHP? ...
I often hear the adage, "Code is read more than it is written." I happen to agree with this sentiment, but I can't find any studies or statistics to back it up. Has anyone come across a substantial finding on this topic (something more than an apocryphal tale) or, better yet, done this sort of research? ...
