What Is the Durbin Watson Statistic? The Durbin Watson (DW) statistic is a test for autocorrelation in the residuals from a statistical model or regression analysis. The Durbin-Watson statistic will always have a value ranging between 0 and 4. A value of 2.0 indicates there is no ...

Explain what the term correlation means as used in statistics. Given a regression, what does the coefficient a of product of multiple variables mean? In multiple regression analysis, explain why the typical hypothesis that analysts want to test is whether a...
A one-way ANOVA uses one independent variable. A two-way ANOVA uses two independent variables. Analysts use the ANOVA test to determine the influence of independent variables on the dependent variable in a regression study. While this can sound arcane to those new to statistics, the applications...
There are many other metrics that can be used to measure loss in a regression. For example, R2 (R-Squared) (sometimes known as coefficient of determination) is the correlation between x and y squared. This produces a value between 0 and 1 that measures the amount of variance that can be...
What is a multiple regression analysis? Regression: Regression is a statistical technique for finding the degree and nature of a relationship between a single dependent variable and a set of independent factors. The goal is to use the values of fixed variables to estimate the values of random va...
Regression (linear and logistic)is one of the most popular method in statistics. Regression analysis estimates relationships among variables. Intended for continuous data that can be assumed to follow a normal distribution, it finds key patterns in large data sets and is often used to determine how...
In general, a linear regression model can be a model of the formyi=β0+K∑k=1βkfk(Xi1,Xi2,⋯,Xip)+εi, i=1,⋯,n, where f (.) is a scalar-valued function of the independent variables, Xijs. The functions, f (X), might be in any form including nonlinear functions or...
Learn what statistical analytics is and how it can be used to collect, analyze, and interpret data. This blog covers statistical analysis types, methods, and more.
A sample is used in statistics as an analytic subset of a larger population. Using samples allows researchers to conduct timely their studies with more manageable data. Randomly drawn samples do not have much bias if they are large enough, but achieving such a sample may be expensive and time...
