    How is conditional main effect interpreted when there is interaction?

    I have a question about multiple regression. May I kindly ask how should I interpret the conditional main effect when the interaction is 0 and the coefficients have opposite signs, more specifically if one of the interaction term contains zero such as angle or time. Please see an example...

    Interpreting regression coefficients from non parametric regression in R (Rfit)

    Hallo, I need to examine the relationship between an outcome variable (continuous) and a number of predictors. Since my data is non-normally distributed (i.e. the residuals from the multiple linear regression are not) I decided to use a rank-based regression using the Rfit function from the...

    Variable that should appear significant is insignificant

    As part of my University research project, I have decided to study the impact of Immigration on house prices but find that the immigration Variable that should be statistically significant according to literature appears to be insignificant. I don't know whether this was down to the method I...

    B value in regression analysis

    Hi all, Please bear with me here. I am new and I also am only learning about statistics & regression analysis. One question about the interpretations of regression coefficient in multiple regression models. I have one variable which comes statistically significant. However it is wrong way...

    Question on Impact of Independent Variable Interpretation

    Hi, Suppose i have a normal linear regression construct, like Sales = Intercept + M1*X1 + M2*X2 + M3*X3 Suppose X1,X2,X3 are the statistically significant variables from the model. I want to create some sort of a simulator which says , for X% increase in X1, what is increase in Y...

    How to Fit polynomial regression by bootstrap and establishing IC of each parameters

    #Hi everybody and excuse me for my bad english for this request on R. #here parameter of an hypothetical interval : x=c(60,59,55,49,43,38,33,28,24,20,17,15,12,10,8,6,5) y=c(59,55,49,43,38,33,28,24,20,17,15,12,10,8,6,5,4) #I adjusted it by a polynomial regression degree 3 (not the best...

    Fama-Macbeth cross-sectional regression interpretation

    Hello everyone, I have applied Fama-Macbeth cross-sectional regression on Fama and French five-factor model (2014). On the left-hand side are the portfolio returns for sixteen size - B/M portfolios. On the right-hand-side are five the factors i.e. market, size, investment, and profitability...

    Combining Standard Errors of 16 portfolios

    Hello everyone, I am working on Fama and French five factor model. I have run regression on 16 size- B/M excess portfolio returns on market premium, size premium, value premium, invesment premium and profitability premium. I have obtained coefficients of these factors, their standard errors...

    Interpretation of coefficients, dependent variable in (%), independent variable in ln

    Hi, I have a very simple question. I have the following equation. My dependent variable is CRES which is the share of renewables in a country's energy supply. My independent variables are log transformed, besides Kyoto which is a dummy variable. CRES= β0 + β1lnGDP + β2Kyoto+...

    evaluating statistical difference between model coefficients: 2 different models

    Hello, I have two logistic regression models with the same dependent and independent variables. The only difference between the 2 models is the way the data are aggregated: one model is based on census tracts, and the other on parcels. I want to determine whether there is a statistically...

    Regression coefficient- need help!!

    Suppose that we have regressed the log of household median income on the Gini coefficient and obtained the following result. Standard errors are listed in parenthesis.: ln(median income)=11.26 − 1.43 ⋅Gini (0.36) (0.80) R2=0.061 no. obs.=51 F(1,49)=3.21 (p=0.079)...
