i'd model distribution mixture of normal , constant 0. i couldn't find solution because in mixture examples i've found class of distribution same every category. here code illustrate i'm looking for: with pm.model() model: x_non_zero = pm.normal(...) zero_rate = pm.uniform('zero_rate', lower=0.0, upper=.0, testval=0.5) fr = pm.bernoulli('fr', p=zero_rate) x = pm.???('x', pm.switch(pm.eq(fr, 0), x_non_zero, 0), observed=data['x']) i'm interested in rate data 0 , parameters of normal when non-zero. here how data i'm modelling looks like: one option try gaussian mixture model, may think of gaussian sd=0 constant value. option use model following: with pm.model() model: mean = pm.normal('mean', mu=100, sd=10) sd = pm.halfnormal('sd', sd=10) category = pm.categorical('category', p=[0.5, 0.5], shape=len(x)) mu = pm.switch(pm.eq(category, 0), 0, mean)

i'm creating new game project, , requires basic interactions between sprites. wondering how implement skphysicscontact class detect when 2 skspritenodes touch. here skphysicscontact class reference: https://developer.apple.com/library/ios/documentation/spritekit/reference/skphysicscontact/#//apple_ref/occ/instp/skphysicscontact/contactnormal i'm not sure how use bodya , bodyb methods detect touches whenever try use it, can't seem figure out how use class. ideas on how use class detect touches between 2 bodies? once scene contact delegate , calls didbegincontact, , didendcontact. these methods uses both body , body b tell whats colliding. there decide want happen when collide, example make bodya = nil.

for example: int age; cin >> age; cout << "you " << age << " years old!" << endl; why use "<<" , ">>" operators here? doing? understand bit-shifting, don't how works here. they called stream insertion operator ( << ) , stream extraction operator ( >> ). these same operators left , right bit shift operators (even though have different names). bit shift operators overloaded, when left side stream, read or write stream. they're function call - works like: leftshift(leftshift(leftshift(leftshift(cout, "you "), age), " years old!"), endl); except function called operator<< instead of leftshift . strictly speaking, there's no reason function called leftshift has left shift, , likewise there's no reason function called operator<< has left shift.

so in publication 5164 (rev. 11-2015) says in 4.3: the manifest requires each transmission carry test file indicator (testfileind) indicate if transmission test or production transmission. however, cannot find anywhere in of xsd files of 7.0. see in old 6.2 xsd files however. still need include this? testfileind in fact remnant of 6.2 , need testfilecd. submitted test scenario 1 no issues without it.

i after plugin or technique in sublime text 3 call qualified path of json element selected in editor window. somethink like: http://jsonpath.com/ i want result somewhere can copy, want use documentation, not programmatically. not need https://github.com/jayway/jsonpath standard, produces readable/meaningful path element.

okay, have 2 simple separate path objects, 1 containing straight line created lineto , 1 containing curve generated quadto function. need point (x, y) these 2 objects insect, once distance 1 side of arc of point intersect. there lots of posts figuring out if intersect, can't find information on how figure out intersect. edit! still can't figure out, i've been trying fake measuring distance along yellow line black lines drawn apart each other , making whole new curve. it's sloppy , not working well. see image! if can distance end black curve intersects yellow line, can segment of curve, , 2 points on it's end, , work great! any ideas, anyone? :) thanks!

at first thought can used performance measurements. said std::chrono::high_resolution_clock may not steady ( is_steady may false ). said std::chrono::high_resolution_clock may alias of std::chrono::system_clock not steady. can't measure time intervals type of clock because @ moment clock may adjusted , measurements wrong. at same time can't convert time points of std::chrono::high_resolution_clock calendar time because doesn't have to_time_t method. can't real time type of clock either. then can std::chrono::high_resolution_clock used for? there none. sorry, my bad . if tempted use high_resolution_clock , choose steady_clock instead. on libc++ , vs high_resolution_clock type alias of steady_clock anyway. on gcc high_resolution_clock type alias of system_clock , i've seen more 1 use of high_resolution_clock::to_time_t on platform (which wrong). do use <chrono> . there parts of <chrono> should avoid. don't

i got sorting algorithm. know have been written in many other , more simple ways that's not point of question. here the algorithm : sort(a : array of n, : n, j : n) assert j-i+1 istwopotency if a[i] > a[j] swap a[i] , a[j] if i+1 < j k:= (j − + 1)/4 sort(a, i, j − 2k) sort(a, j − 2k + 1, j) sort(a, + k, j − k) sort(a, i, j − 2k) sort(a, j − 2k + 1, j) sort(a, + k, j − k) my question is, why algorithm work correctly in following case? sort(a, 1, length(a)) and array be: a[1 . . . length(a)] length(a) 2 potency , can assume there no identical numbers inside array . tested it, got no errors assume works correctly. how can prove algorithm works correctly in these conditions? and wondering how long algorithm needs running time. great if give me running time big theta notation (that's 1 understand best) f(n) = Θ(g(n)) correctness divide array 4 quarters, a1 through a4, , consider sub-array each element should end i
