Multiple linear regression (MLR) is a statistical technique that uses several explanatory variables to predict the outcome of a response variable. It models the linear relationship between the explanatory and response variables and is widely used in econometrics and financial inference. MLR assumes a linear relationship, independent observations, and normally distributed residuals, but can face challenges like multicollinearity and overfitting. Find out more at the link in our bio.
A chi-square (χ²) statistic is like the detective of the data world, comparing your model to the real-world observations and revealing how closely they match! This handy tool shines in hypothesis testing, helping researchers uncover if two variables are connected or stand alone. With its focus on categorical data, the chi-square statistic invites us to explore the intriguing stories behind the numbers—are they fitting the expected patterns, or is there something surprising lurking beneath the...
Statistics is a branch of applied mathematics focused on collecting, analyzing, and interpreting data to draw conclusions about larger populations from smaller samples. Statisticians use various methods to summarize data and make inferences, playing a crucial role in fields like business, government, and science. Essentially, statistics helps us understand trends and make informed decisions based on data! Read more at the link in our bio.
