Linear analysis is one type of regression analysis. For example, the equation for a line is y = a + bX. Y is the dependent variable in the formula, which one tries to predict what will be the future value if X, an independent variable, changes by a certain value. The “a” in ...
The correlation coefficient measures the relationship between variables numerically. On the other hand, a scatter plot can be used to check the relationship between the variables graphically. So, the scatter plot tells if there is any linear relationship or not...
Machine learning.Logistic models can also transform raw data streams to create features for other types of AI andmachine learning techniques. In fact, logistic regression is one of the commonly used algorithms in machine learning for binary classification problems, which are problems with two class v...
Analysis of variance (ANOVA) is a statistical test used to compare the means of multiple groups. Learn what is ANOVA, its formula, types, applications, etc.
"Say you run a regression in excel with a sample size of 2,000 and the T-stat reported is 0.41. What should you conclude about this variable's coefficient (Critical Value: 1.96)?" Explain your answer. You are told that the coefficient of determin...
In other words, the relationship is so predictable that the value of one variable can be determined from the matched value of the other. The closer the correlation coefficient is to zero, the weaker the correlation, until at zero no linear relationship exists at all. ...

-1: This is a perfect negative correlation. The variables are related, but they move in opposite directions from one another. As one increases, the other will decrease. One way to calculate whether or not there’s a positive correlation is to run a regression analysis on the two variables,...
