1. What is regression analysis sample size problem? The regression analysis sample size problem refers to the issue of determining the appropriate number of observations or data points to include in a regression analysis. This is important because a sample size that is too small may not ...
Regression analysis is an important tool for modelling and analyzing data. Here, we fit a curve / line to the data points, in such a manner that the differences between the distances of data points from the curve or line is minimized. I’ll explain this in more details in coming sections...

The independent variables should not be correlated with each other i.e.no multi collinearity. However, we have the options to include interaction effects of categorical variables in the analysis and in the model. If the values of dependent variable is ordinal, then it is called asOrdinal logisti...
The results of the multiple regression analysis for the overall sample showed that: 18% (Adjusted R2) of the variance in word recognition scores was accounted for by the visual processing factor and the retrieval/hook-up factor added an additional 69% (Adjusted R2); and that 17% (Adjusted ...
’s may be biased), and/or over/underestimate the S.E.R. of the model (that is, our estimate of the S.E.R. may be biased) Clearly, the three problems in the bulleted list above are serious. After all, the main point of regression analysis is to estimate the b’s, and ...
