I'm trying to fit a multiple linear regression model to my data with couple of input parameters, say 3. Sample size calculation for logistic regression is a complex problem, but based on the work of peduzzi et al. (1996) the following guideline for a minimum number of cases to include in your study can be …

However, my dependent variable has the following plot: Here is a scatterplot matrix with all my variables (war is the dependent variable): I was just wondering why regression problems are called regression problems. What is the story behind the name? One definition for regression: Relapse to a less perfect or developed state. Hence, if the sum of squared errors is to be minimized, the constant must be chosen such that the mean of the errors is zero. ) in a simple regression model, the constant represents the y-intercept of the …
