Assumption #4: There needs to be a linear relationship between (a) the dependent variable and each of your independent variables, and (b) the dependent variable and the independent variables collectively. You can check for linearity in Stata using scatterplots and partial regression plots. Assumpti...
A multiple linear regression model was constructed for the reported response rates of studies investigating the prevalence of female sexual difficulties. All statistical analyses were performed with Stata version 8 (StataCorp, College Station, TX, USA). ...
These parameters have been computed using various data mining tools like SPSS, XLstat, Stata, and MS-Excel. It is seen that for all the given dataset, factor analysis outperform multiple linear regression. But the absolute value of prediction accuracy varied between the three datasets indicating ...

看Treiman在stata里对付curvelinear的时候,我就发现,其实这个在大家眼里早已不是什么秘密,尤其是用mean控制变量,用lowess探索。spss还不具备lowess功能,这一点stata倒是很不错。其他部分,则流于浅显,这是因为本书试图覆盖太多的东西。结果难免力不从心,或者,我不感兴趣。回京的路上看黑暗森林,两个不同星球的猎手...
Here, we can employ a linear regression model in cases where the dependent variable is affected by two or more controlled variables. The linear multiple regression equation is expressed as: (1-47)Y=C0+C1X1+C2X2+…+CKXK where Y = the dependent variable X1, X2,…...
Negative associations between multiple sclerosis-related disability and Personal Wellbeing Index life domains, obtained through multivariable linear regression. Notes: Data are presented as coefficient (standard deviation); no MS-related disability was the base category. A separate, linear multivariable regre...
