We consider the problem of fitting a relationship (e.g., potential scientific law) to data involving multiple variables. Ordinary (least squares) regression is not suitable for this because estimated will differ according which variable chosen as being dependent, and dependent unrealistically assumed be only has any measurement error (noise). present very general method estimating linear functi...

The present work deals with fitting literature data of ASTM Distillation curves and obtain a new correlation suitable to use in modeling when optimizing the refining processes, such as distillation, FCC, catalytic reforming, hydrotreating, etc.
 results showed that values predicted by are very good agreement range mean overall deviation (%MOD) is (0.305-0.585).

Structural equation models are commonly used to capture the relationship between sets of observed and unobservable variables. Traditionally these fitted using frequentist approaches, but recently researchers practitioners have developed increasing interest in Bayesian inference. In settings, inference for is typically performed via Markov chain Monte Carlo methods, which may be computationally ...

cash flow forecasting is an indispensable tool for construction companies, and is essential for the survivalof any contractor at all stages of the work. the time available for a detailed pre-tender cash flow forecast is oftenlimited. therefore, contractors require simpler and quicker techniques which would enable them to forecast cash flowwith reasonable accuracy. forecasting s-curves in constr...

One of the basic equations to analyze the detonation of high explosives is the equation of state of the detonation products. Due to the very high pressure of the product, the direct measurement of the thermodynamic variables such as pressure or temperature is not possible. In this research, the parameters of BKW and HOM equations of state of detonation products are determined via experimental m...
