Key Takeaways A back-of-the-envelope calculation is a quick and informal mathematical computation. This type of calculation is used as an estimate to arrive at a ballpark figure when needed quickly.

The results of various calculations show that there is a deviation of more than 10 m among the different methods of calculation for a directional well of 3,000 m. 1 Consequently, it is important ...

For the Poisson regression model, an exact expression for Fisher's information matrix, based upon the moment generating function of the distribution of covariates, is calculated. This parallels a ...
