Linear RegressionSeveral studies have been conducted in the Project Management field further to improve the Earned Value Management (EVM) methodology to forecast the project cost estimate at completion (EAC). This work aims at developing a linear model to increase the accuracy of the standard EAC ...
If this relationship can be estimated, it may enable us to make more precise predictions of the dependent variable than would be possible by a simple linear regression. Regressions based on more than one independent variable are called multiple regressions. Multiple linear regression is an exte...
1. Binomial logistic regression model 尽管线性分类器方法足够简单并且使用广泛,但是线性模型对于输出的 y 没有界限,y 可以取任意大或者任意小(负数)的值,对于某些问题来说不够 adequate, 比如我们想得到 0 到 1 之间的 probability 输出,这时候就要用到比 linear regression 更加强大的 logistic regression...
MLR is used to study the collaboration of the relationships of two or more variables that affect another value. The regression includes various linear regressions and logistic regression algorithms that control the learning model to predict the input data into the program71. Its algorithms are more ...
Inference is based on the multiple regression linear model, which specifies that the observed value for Y is equal to the population relationship plus independent random errors that have a normal distribution Y=(α+β1X1+β2X2+…+βkXk)+ε=(Populationrelationship)+Randomness where ε has a nor...
with a time lag of 9 h identified for pressure and 26 h for wind stress. A multiple linear regression model was then employed to estimate the expected intensity of the storm surge. The results suggest that the model represented 82% of the variations in the storm surge levels. The accuracy...

Currently, the methods used in cohort studies in Japan to calculate nutrient intakes for FFQs include an empirical weights approach22, but the dependent variable used in the multivariable linear regression was nutrient intake from a weighed dietary food record. In addition, methods have been ...
In this study, daily average PM2.5 forecasting models were developed and applied in the Northern Xinjiang, China, through combining the back propagation artificial neural network (BPANN) and multiple linear regression (MLR) with another BPANN model. The meteorological (daily average precipitation, pre...
