问题 As a reproducible example, let's use the next no-sense example: > library(glmmTMB) > summary(glmmTMB(am ~ disp + hp + (1|carb), data = mtcars)) Family: gaussian ( identity ) Formula: am ~ disp + hp + (1 | carb) Data: mtcars AIC BIC logLik deviance df.resid 34.1 41.5 -12.1 24.1 27 Random effects: Conditional model: Groups Name Variance Std.Dev. carb (Intercept) 2.011e-11 4.485e-06 Residual 1.244e-01 3.528e-01 Number of obs: 32, groups: carb, 6 Dispersion estimate for gaussian family (sigma^2):

问题 I have 2 lists. The first is list_A = ['Sasi', 'Babu', 'kuttapppan', 'mathayi'] and my second list is list_B = ['Raman', 'Kesavan', 'sasi', 'unni', 'Kuttappan'] . I want to compare these two lists and identify the values which are duplicated in the second list regardless of if it starts with a capital letter or a lowercase letter. I've tried the following method: if not [name for name in list_A if name in list_B]: print name But it is not working as expected. 回答1: #Might be better if we are

问题 I am trying to compare two files and each line is in JSON format. I need to compare each line between two files and should return the difference.Since the file size is too big and I am unable to read and compare each line.Please suggest me some optimised way in doing this. 回答1: Two possible ways : Using the technique mentioned in the comment posted by Josh. Using the technique mentioned here : how to compare 2 json in python. Given that you have a large file, you are better off using difflib

问题 How would I go about writing my own eqv? or equal? in scheme? Would I just do a cond and look for symbol?, number?, etc and return the appropriate #t or #f? 回答1: As per R5RS, the minimum specifications for an implementation of eqv? (when passed two arguments obj1 and obj2 ) to evaluate to #t are: obj1 and obj2 are both #t or both #f . (how two boolean literals evaluate to the same value is implementation dependent). obj1 and obj2 are both symbols and (string=? (symbol->string obj1) (symbol-

问题 I'm refactoring a library and trying to get rid of many gcc warnings. The big part of these warning are about signed / unsigned comparison and are related to the usage of size_t . The library works on 64 bit Linux systems. A programmer used -1 as the special value similar to std::string::npos . There are many places in the library where code looks like this: class AnnotationBase { public: size_t m_offset = -1; size_t m_length = -1; } ... AnnotationBase foo(const std::string& text, const

问题 I have the following function: def InRange(number): return 5 <= number >= 1 I want this to say false if the number is not within the range of 1 to 5 using a chain comparison, but cannot seem to get this right. Any suggestions? 回答1: You want it like this: def InRange(number): return 1 <= number <= 5 Note that you could also do: def InRange(number): return 0 < number < 6 回答2: Use this: 1 <= number <= 5 From docs: x < y <= z is equivalent to x < y and y <= z , except that y is evaluated only

问题 I'm studying how Hooks APIs provided by React-Redux-v.7.1 works, and saw it mentioned in Equality Comparisons and Updates (https://react-redux.js.org/api/hooks#equality-comparisons-and-updates) that: " As of v7.1.0-alpha.5, the default comparison is a strict === reference comparison. This is different than connect() , which uses shallow equality checks on the results of mapState calls to determine if re-rendering is needed. This has several implications on how you should use useSelector() . "

问题 How to check if two series of dates overlap and determine the first date that it occurs? Imagine that I've created two events in Google Calendar. One of them in Date1 and repeating every X days; the other in Date2 and repeating every Y days. What would be the best algorithm to determine if the two series will overlap someday, and find the first date that it would happen? Example 1: Date1 = Feb-15, 2016 X = 14 (repeat every 14 days) Date2 = Feb-22, 2016 Y = 21 (repeat every 21 days) Result:
