def sample(): u=np.random.rand() #这里出现local variable 'u' is assigned to but never used怎么解决 if u <= 0.1: dic["居家办公"] += 1 elif u <= 0.3: dic["休息"] += 1 else: dic["正常上班"] += 1 def sampleNtimes(): for i in range(10000): sample() for k,v in dicitems(): print (k,v)
The random variable X is normally distributed with mean u. A random sample of12 observations is taken on X, and it is found that$$ \sum _ { i = 1 } ^ { 1 2 } ( x _ { i } - \overline { x } ) ^ { 2 } = 9 9 . $$Determine a 95% confidence interval for u. 相关...

A simple stand-alone scanning tunnelling microscope (STM) has been designed and constructed. It employs a spring-diaphragm assembly for a coarse approach and a concentric tube assembly as the scanner. It is functionally capable of STM operation (constant current, constant height, line test) and ...
Random user point removal: This operator randomly removes user points from the drone’s route until the removal requirement is met. Worst user point removal: For each user point, this operator calculates the difference between the cost function with and without this user point. The cost function...
