distribution

问题 if you have a product and would like to have an iPhone Application for this commercial product (this application just communicates with web service and presents some data) how can you distribute this iPhone-App by customers of this product? only about Apple-Store? Would Apple allow to store there an application for the commercial product? Can be this application free? Thank you so much! Best regards. 回答1: Absolutely. There are many products like this in the App Store already. You will just

问题 Given the following function: f(x) = (1/2*pi)(1/(1+x^2/4)) How do I identify it's distribution and write this distribution function in R? 回答1: So this is your function right now (hopefully you know how to write an R function; if not, check writing your own function): f <- function (x) (pi / 2) * (1 / (1 + 0.25 * x ^ 2)) f is defined on (-Inf, Inf) so integration on this range gives an indefinite integral. Fortunately, it approaches to Inf at the speed of x ^ (-2) , so the integral is well

问题 I have a code that create 16 histograms. My problems are: I think the code is too much repetative and that there are ways to write it shorter. 2.I have 13 fields to create histograms, and as 13 is prime number, I face a problem how to show all of them nicely but without blank plots. I want to show the distribution but I get only 1 bar, even though I have change dit to 0, 100 and 500 (I have more than 1000 observations). some columns are float and have too many 0 after the dot and I can't

问题 I have a follow up question to Sasha's answer of my earlier question at TransformedDistribution in Mathematica. As I already accepted the answer a while back, I thought it made sense to ask this as a new question. As part of the answer Sasha defined 2 functions: LogNormalStableCDF[{alpha_, beta_, gamma_, sigma_, delta_}, x_Real] := Block[{u}, NExpectation[ CDF[StableDistribution[alpha, beta, gamma, sigma], (x - delta)/u], u \[Distributed] LogNormalDistribution[Log[gamma], sigma]]]

问题 I am currently trying to cut an interval into not equal-width slices. In fact I want the width of each slice to follow a logarithmic rule. For instance the first interval is supposed to be bigger than the second one, etc. I have a hard time remembering my mathematics lectures. So assuming I know a and b which are respectively the lower and upper boundaries of my interval I , and n is the number of slices: how can I find the lower and upper boundaries of each slice (following a logarithmic

问题 I'm thinking of developing a small application using IronPython, however I want to distribute my app to non-techies and so ideally I want to be able to give them a standard shortcut to my application along with the instructions that they need to install IronPython first. If possible I even want my shortcut to detect if IronPython is not present and display a suitable warning if this is the case (which I can do using a simple VbScript) The trouble is that IronPython doesn't place itself in the

问题 Access to a Frozen Distribution's Name When creating a frozen distribution from the scipy.stats package, how can the distribution's name be accessed once the distribution instance is frozen? Trying to access the .name attribute produces an error since it is no longer an attribute of the rv variable. import scipy.stats as stats # Get the name of the distribution print 'gamma :', stats.norm.name # Create frozen distribution rv = stats.norm() # Get the name of the frozen distribution print 'rv :

问题 I would like to distribute an App preview to a musician that I am working with. He is not an employee of my company but offered me to do the game sountrack for free. I have checked on the iOS Provisioning Portal and found the following dislcaimer: "Important: Your iOS Developer Program membership can be terminated if you provide pre-release Apple Software to anyone other than employees, contractors, and members of your organization who are registered as Apple Developers and have a

问题 I have a simple desktop Ruby client which I would like to distribute to a small number of (technical and non-technical) people. The client will run as a daemon, hence there is no GUI. I only need the client to run on OSX and Linux. Is there a way that I can distribute a certain version of Ruby with the application and run my client using that version? How would I do this? 回答1: Yes, but it's probably prohibitively complicated. Ruby needs to be compiled for the platform you're running it on, so

问题 I am trying to include a number of text files as resources in my runnable .jar-file. The following code should print the contents of one file: URI resourceFile = Driver.class.getResource("/etc/inputfile.txt").toURI(); System.out.println("Opening URI: " + resourceFile.toString()); File infile = new File(resourceFile); Scanner sc = new Scanner(infile); while (sc.hasNextLine()) System.out.println(sc.nextLine()); sc.close(); After exporting as a runnable jar, I get the following output when
