The shape parameter, k, is that power plus one, and so this parameter can be interpreted directly as follows: If the quantity x is a “time-to-failure”, the Weibull distribution gives a distribution for which the failure rate is proportional to a power of time. Its complementary cumulative distribution function is a stretched exponential function. K \frac & x\geq0 \\Ġ & x 0 is the shape parameter and \(\lambda > 0\) is the scale parameter of the distribution. reshape (( ndata / 10, 10 )), axis = 1 ), bins = nbins ) axs. reshape (( ndata / 2, 2 )), axis = 1 ), bins = nbins ) axs. subplots ( 1, 3 ) #t(14) #sns.set_context('paper') #sns.set_style('whitegrid') axs. random ( ndata ) # Show them fig, axs = plt. set ( context = 'poster', style = 'ticks' ) def main (): '''Demonstrate central limit theorem.''' # Generate data ndata = 1e5 nbins = 50 data = np.
