i want estimate parameters of non linear model. the model equation z = * exp(- * x) + b * exp(- b * y) + c x , y predictors a, b, a, b parameters estimate what did transform model linear problem doing exponential transformation before doing linear regression: for a , b between 0 , 1, compute exp_x = exp(- * x) , exp_y = exp(- b * y) i linear regression z ~ exp_x + exp_y it works can see in simulation x = 1:10 y = 1:10 combination = expand.grid(x = x, y = y) df = data.frame( x = combination$x, y = combination$y, z = 2 * exp(-0.3 * combination$x) + 5 * exp(-0.6 * combination$y) + rnorm(n = 100, mean = 0, sd = 0.1 ) ) a_hat = 0 b_hat = 0 best_ols = null best_rsquared = 0 (a in seq(0.01, 1, 0.01)){ (b in seq(0.01, 1, 0.01)){ df$exp_x = exp(- * df$x) df$exp_y = exp(- b *df$y) ols = lm(data = df, formula = z ~ exp_x + exp_y) r_squared = summary(ols)$r.squared if (r_squared > best_rsquared){ best_rsquared =...

i'm developing app sends mpeg2ts stream using ffmpeg api.(avio_open, avformat_new_stream etc..) the problem app has aac-lc audio audio frame not need encoded because app bypass data received socket buffer. to open , send mpegts using ffmpeg, must have avformattcontext data created ffmpeg api encoder far know. can create avformatcontext manually encoded aac-lc data? or should decode , encode data? information know samplerate, codec, bitrate.. any appreciated. in advance. yes, can use encoded data as-is if container supports it. there 2 steps involved here - encoding , muxing. encoding compress data, muxing mixes in output file, packets interleaved. muxing example in ffmpeg distribution helped me this. you might take @ following class: https://sourceforge.net/p/karlyriceditor/code/head/tree/src/ffmpegvideoencoder.cpp - file 1 of projects, , contains video encoder. starting line 402 you'll see setup non-converted audio - kind of hackish way, worked. unfortu...

i have vs2015 + cordova + typescript project includes unit testing. have tests folder unit .spec.ts files. is possible exclude folders (example ./scripts/test ) in root /scripts folder when publishing , still keep typescript intellisense excluded folder? note: aware of adding exclude attribute tsconfig.json file, when loose intellisense in .spec.ts files in ./scripts/test folder. ideally, when unit testing, run gulp script ( karma + jasmine ) compile ./script typescript files , place .karma folder. when publish project ios, android, windows devices using vs2015 exclude unit test file in app. it's not big problem, improve workflow , still rely on vs2015 publish mobile devices. maybe adding gulp file after build binding cleanup www/script/**/*.spec.js files solution?

our project development effort uses visual studio 2013 on our government client laptops, pull source code visual studio team services (externally). best approach setup continuous integration & delivery on our government servers (dev, staging , prod)? none of servers have internet access. you need continuous integration server installed on 1 of machines access visual studio team services, can setup tasks on ci server deployment on other machines not have access vsts. use teamcity ci server of choice, other ci servers have similar capabilities. to setup teamcity vsts see http://blog.jetbrains.com/teamcity/2014/09/teamcity-and-visual-studio-online-source-control/ to setup teamcity deploy asp.net applications see https://blog.jetbrains.com/teamcity/2014/04/continuous-delivery-to-iis-or-windows-azure-web-sites/

i developing android studio plugin using intellij , want component size(button or textview's width,height ) in intellij plugin. in picture, wrote code height="wrap_content" , width "wrap_content" . i want know button size( dp or px number). also when textview or component defined wrap_content , don't know width , height. i think, android studio components has default width , height. don't know defined! thank you! the default size android:minheight attribute set 48dip default. and take look: http://developer.android.com/reference/android/view/viewgroup.layoutparams.html wrap_content , means view wants big enough enclose content (plus padding) and of course: https://stackoverflow.com/a/23984754/4409113
