Suppose that you want to perform a product reliability acceptance test, whereby you guarantee that a product will meet some MTTF target based on an exponential distribution with 1 –α confidence. You can estimate the length of time you need to run the test by using the following Exce...

For the exponential distribution, the pdf is and so the likelihood function for a data set {x1,…, xn} is Maximizing L(λ) is equivalent to maximizing the log-likelihood function LL(λ) = ln L(λ). It turns out that LL is maximized when λ = 1/x̄, which ...

The first is to show that the limiting distribution in (30) can be simplified to: (31)B12-ρ-1Bρ2+lnρ, and can be simulated by 1-ρZ12-Z22+lnρ, where Z1 and Z2 are independent standard normal random variables. This limiting distribution is much simpler than the one derived in...
The Exponential distribution is sometimes used to define events, such as the occurrence of earthquakes or rockbursts, or quantities such as the length of joints in a rock mass. Of the currently defined statistical variables inUnWedge, you may find an exponential distribut...
The exponential distribution optimizer (EDO) represents a heuristic approach, capitalizing on exponential distribution theory to identify global solutions for complex optimization challenges. This study extends the EDO's applicability by introducing its multi-objective version, the multi-objective EDO (MOEDO...
aThis system's main functions are importing data, packaging data to zip files and generating reports. The reports are excel and word files, most of formats are controlled by VBA code. The database is MS SQL 2005, this system also used Stored procedure and Views. 这个系统的主函数进口数据,...
To come up with a better algorithm given the actual distribution, we can use induction to make the optimal decision at each step. If I’m down to my last date, I have to be happy with whatever I get – the average is 5.8.
