Python _lazyselect示例

示例#1

	def logpdf(self, x):
		r = _lazyselect([x < self.lower_bound,
						 (self.lower_bound <= x) & (x <= self.upper_bound),
						 x > self.upper_bound],
						[lambda x: 0,
						 lambda x: self.frozen_dist.logpdf(x)-np.log(self.untruncated_mass),
						 lambda x: 0],
						(x, ))
		return r

示例#2

	def cdf(self, x):
		r = _lazyselect([x < self.lower_bound,
						 self.lower_bound <= x <= self.upper_bound,
						 x > self.upper_bound],
						[lambda x: 0,
						 lambda x: ((self.frozen_dist.cdf(x)-self.mass_below_lower_bound)
									*self.untruncated_mass),
						 lambda x: 1],
						(x, ))
		return r
