By using the traditional multiple regression on all the predictor variables, it is possible to have problems with interpretation and multicollinearity. As an alternative to multiple regression, we explore the use of a latent variable model that can address the relationship among the predictor variables...
216K Learn the three ways to solve two-variable equations. Study how to solve it algebraically with substitution or elimination and graphing on a coordinate plane. Related to this QuestionWhat is a linear equation in two variables? What is a linear equation in one variable? Which of the fol...
摘要: We formulate a joint statistical model for two variables: one of them is either a count variable or just zero, and the other is a regular count variable. We consider a modelling framework based on...关键词: Bank card payments Bayesian inference Bivariate Poisson regression model Cash ...
A regression equation was obtained to predict the power values using the weight of an individual and the ‘jump and reach’ height as independent variables. The regression equation is given by p = ‐666.3+14.74 [Mass (kg)] +1925.72 [Height (m)]; [R‐square = 0.69, p<0.05]. 展开...
I am estimating an equation: Y = a + bX + cZ + dW I then want to instrumentWwithQ. I know the first-stage regression is supposed to be W = e + fX + gZ + hQ (i.e., use all the exogenous variables in the first stage). Actually this is automatically done if I use theivreg...

GraphPad Prism uses this method to compare two linear regression lines. Two-way ANOVA to compare curves, without a model It is also possible to compare two curves, without fitting a model using two-way ANOVA. The two factors are treatment and whatever variable is coded by X (usually time ...
