i have inline variadic function inline int foo(...) i need foo() call macro (let's call macro ), variadic. need foo() pass input parameters macro . redefining foo() macro easy solution because of __va_args__ option, need foo() return value. note: trying interface 2 parts of written code , not allowed change them. foo(...) used in first part of code , macro defined in second part. thing supposed define foo() uses macro , can't because both variadic. make foo macro contains lambda returns value, , invokes lambda. #define foo(...) \ [&](auto&&...args){ \ /* args, or __va_args__ */ \ macro(__va_args__); \ return 7; \ }(__va_args__) now int x = foo(a, b, c); both call lambda inside foo , , inside lambda call macro on (a, b, c) , , can return value. i pity whomever maintains code next.

currently work on calibration of probability. use calibration approach, called rescaling algorithm - source http://lem.cnrs.fr/portals/2/actus/dp_201106.pdf (page 7). the algorithm wrote is: rescaling_fun = function(x, y, z) { p_korg = z # yhat_test_prob$bad p_k_c1 = sum(as.numeric(y) - 1)/length(y) # testset$bad p_kt_c1 = sum(as.numeric(x) - 1)/length(x) # trainset$bad p_k_c0 = sum(abs(as.numeric(y) - 2))/length(y) p_kt_c0 = sum(abs(as.numeric(x) - 2))/length(x) p_new <- ((p_k_c1/p_kt_c1) * p_korg)/((p_k_c0/p_k_c0) * (1 - p_korg) + (p_k_c0/p_k_c1) * (p_korg)) return(p_new) } the input values are: 1. x - train_set$bad (actuals of `train set`) 2. y - test_set$bad (actuals of `test set`) 3. z - yhat_test_prob$bad (prediction on `test set`) the problem - result values not within range of 0 , 1 . please solve problem? your formulas obtain probs ( p_k_c1 ...) need modified. example, according paper, y binary variable (0, 1) , fo

(relatively new ios developer) i building drill-down table , data read plist file. data dictionary @ root of plist needed order maintained. it's array, @ expense of needing additional formatting extract data. there 2 view controllers (master/detail) need access method. there 2 options i'm thinking unsure implement: create utility class class helper methods can go okay have class contains mixed bag of methods utility use? create category on viewcontroller. category used 2 view controllers , there 1 method in category. i learn if there better practices out there this? thank you! this may answering more general question asking but: if have not come across take @ model-view-controller (mvc) design pattern advocated apple.

i've seen multiple responses around type of question, don't believe i've seen type of list concerned with. not duplicating here. appreciated! i have comma separated file use data enrichment. starts headers - tpcode,corporation_name - list of values follows. there around 35k rows (if matters). i notice when data lookup file (csv) displayed there multiple entries same customer. rather going in , manually removing them, run python script remove duplicates in format of: value,value value,value value,value etc., optimal way remove duplicates using python? side note, each tpcode should different, corp name can have multiple tpcodes. please let me know if need additional information. thanks in advance! hard tell question if each line should unique. if do: for l in sorted(set(line line in open('ors_1202.log'))): print(l.rstrip()) otherwise need more info.
