i'm looking script/package in r (python too) find out component distribution parameters mixture of gaussian , gamma distributions. i've far used r package "mixtools" model data mixture of gaussians, think can better modeled gamma plus gaussian. thanks here's 1 possibility: define utility functions: rnormgammamix <- function(n,shape,rate,mean,sd,prob) { ifelse(runif(n)<prob, rgamma(n,shape,rate), rnorm(n,mean,sd)) } (this made little bit more efficient ...) dnormgammamix <- function(x,shape,rate,mean,sd,prob,log=false) { r <- prob*dgamma(x,shape,rate)+(1-prob)*dnorm(x,mean,sd) if (log) log(r) else r } generate fake data: set.seed(101) r <- rnormgammamix(1000,1.5,2,3,2,0.5) d <- data.frame(r) approach #1: bbmle package. fit shape, rate, standard deviation on log scale, prob on logit scale. library("bbmle") m1 <- mle2(r~dnormgammamix(exp(logshape),exp(lograte),mean,exp(l

i trying populate combobox mysql database; don't anything. below code. table: class columns: code, state sqlstr = "select * class state= not started" dbcmd = new mysql.data.mysqlclient.mysqlcommand(sqlstr, dbconn) dbdr = dbcmd.executereader while (dbdr.read()) cb_class.items.add(dbdr("code")) end while dbcmd.dispose() dbdr.close() i believe result wrong, because there @ least 2 records state values set "not started". wrong? there wrong way i've written "state= not started" ? the command text doesn't seems correct. lacks single quote around string search sqlstr = "select * class state='not started'" ^ ^ if state string field every search on should enclosed in single quotes. beware of potential problems when string search contains single quote. in simple case use directly string constant, if render search dynamic user input should use para

i have cell prototype i'm trying add 2 labels to. have 2 labels right next each other, size of labels dynamic, want second label able shift depending on size of first label. basically, want there fixed gap between 2 labels, 2 labels' sizes dynamic. how do that? edit: actually found out how via storyboard. if select 2 labels want have fixed gap between, command select both of them , go corner of storyboard , click pin menu, little 'h' looking thing in group of buttons near zoom in/zoom out in bottom right corner of storyboard screen. get label size method: - (cgsize)sizewithfont:(uifont *)font https://developer.apple.com/library/ios/#documentation/uikit/reference/nsstring_uikit_additions/reference/reference.html . then set label's textalignment nstextalignmentleft , nstextalignmentright, , set frames string size , other offset.

often have been browsing q & site, answers use multi-threading , processing have told me use format goes this: (target=foo, args=(bar, baz)) it used in multiprocessing , multithreading (at least limited knowledge.) my question is, what target mean, , can explain how used? i have not been able find explanation in docs or elsewhere. the keyword argument target in threading.thread 's constructor sets entry-point of new thread. can function or object has __call__ method. here's example using function: import threading def foo(number, name): print 'hello new thread' print 'here arguments:', number, name thread = threading.thread(target=foo, args=(5,'bar')) thread.start() thread.join()

the function below 2 things - checks if atom nil or fetch-agin true, , fetches data. it processes data calling (add-date-strings). what better pattern separate out above 2 concerns ? (def retrieved-data (atom nil)) (defn fetch-it! [fetch-again?] (if (or fetch-again? (nil? @retrieved-data)) (->> (exec-services) (map #(add-date-strings (:time %))) (reset! retrieved-data)) @retrieved-data)) one possible refactoring be: (def retrieved-data (atom nil)) (defn fetch [] (->> (exec-services) (map #(add-date-strings (:time %))))) (defn fetch-it! ([] (fetch-it! false)) ([force] (if (or force (nil? @retrieved-data)) (reset! retrieved-data (fetch)) @retrieved-data))) by way, pattern seperate out concerns called "functions" :)

i'm new python , i'm working code requires me make use of regular expressions substantially. i've gone through python documentation regular expressions ( http://docs.python.org/2/library/re.html ) however, since i'm new python find hard implement functions specified within documentation data need work with. i wondering if there's forum out there explains regular expressions in python multiple examples each function , possible variations. more merrier. i've found ( http://docs.python.org/2/howto/regex.html ) , ( http://flockhart.virtualave.net/rbif0100/regexp.html ) far. i've found them useful wondering if there out there that's better. you can try pythonregex , python specific , generates python code regular expressions. enjoy!

i working on udp server/client applicataion. since communicating server, clients must know ip address , port number of server. purpose, have hard coded ip , port number of server clients everytime, client connects same ip , port number.

through iteration construct big matrix , in order speed these iterations split matrix chunks put in list. would have better save chunks of matrix text file , append new chunk on same text file instead of keeping them in list. change in terms of memory use , performence (time run simulation) ? second question: there way know memory size of r object (without having save .rdata file) thank in advance ! retain matrix in ram if possible. else can bigmemory package . and latest version of r has better support large vectors. helpful if have 64-bit machine large amounts of ram. note:since talking performance, practice pre-allocate matrix (instead of frequent use of rbind / cbind)

i tried using following code read number of available bytes in socket (on server side) , variable packet_bytes not anything. expecting number of bytes used packet read packet_bytes doesn't seem work. std::size_t packet_bytes = 0; socket_.async_read_some(boost::asio::buffer(data_, max_length), boost::bind(&session::handle_read, this, boost::asio::placeholders::error, packet_bytes)); i tried std::size_t packet_bytes = socket_.available(); , didn't return either. entire code . the packet_bytes argument in bind call should placeholder: socket_.async_read_some(boost::asio::buffer(data_, max_length), boost::bind(&session::handle_read, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); then in handler function argument amount of bytes read. see e.g. example in manual .

i have homework assignment of coding bidirectional bubble sort. can please see if logic correct respect it. don't want code want figure out myself. want logic check of how understand it. as understand bidirectional bubble sort implement 2 loops 1 starting @ position 1 in list , performing normal bubble sort. first loop reaches end second 1 implemented working in reverse. don't understand terminating conditions each loop be. would loop conditions follows? loop 1 - for(i = 0; < count -i; i++) loop 2 - for(j = count - i; j > i; j--) in each loop swap conditions specified. thanks the "classic" bubble sort goes through entire array on each iteration, loops should be for(i = 0; < count - 1; i++) and for(j = count - 1; j > 0; j--) both loops skip 1 index: first loop skips last index, while second loop skips initial one. code safely compare data[i] data[i+1] , , data[j] data[j-1] . edit "optimized" bubble sort skips
