Worst Predictor

A variable in a statistical model that contributes least to the prediction of the outcome variable, often due to lack of significant correlation or variability.

SE Coef

The Standard Error of the Coefficient (SE Coef) measures the accuracy with which a sample represents a population, specifically showing how much the estimated coefficients of a regression analysis are likely to vary from the actual population values.

Linear Effects

Phenomena or changes that are directly proportional to the changes in an independent variable, showing a straight-line relationship in graphical representations.

Worst Predictor

A variable or factor that provides little to no useful information in forecasting or predicting outcomes.
