Beta, specifically, is the slope coefficient obtained through regression analysis of the stock return against the market return. You can use the following regression equation to estimate the beta of the company: ΔSi=α+βi×ΔM+ewhere:ΔSi=change in price of stock iα=intercept value of ...
Standardized regression coefficients remove the unit of measurement of predictor and outcome variables. They are sometimes called betas, but I don’t like to use that term because there are too many other, and too many related, concepts that are also called beta. There are many good reasons to...
One the most basic tools for engineering or scientific analysis is linear regression. This technique starts with a data set in two variables. The independent variable is usually called "x" and the dependent variable is usually called "y." The goal of the technique is to identify the line, y...

These can have a very negative effect on the regression equation that is used to predict the value of the dependent variable based on the independent variables. You can check for outliers, leverage points and influential points using Stata. Assumption #8: The residuals (errors) should be ...
Essentially, in logistic regression we fit an s-shaped curve to the training data. Specifically, we fit a function to the training data of the form: (1) The equation above is for a model with one X variable (feature), but it generalizes to multiple features. ...
I am using the linear regression with quadratic terms to fit the variable "C" as a function the variables "H2O", "CO2" and "P". I have exported the compact model into my workspace: When I open the structure and click on "LinearModel", I find the supposedly used equation ...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
To better understand how network structure shapes intelligent behavior, we developed a learning algorithm that we used to build personalized brain network models for 650 Human Connectome Project participants. We found that participants with higher intell
If you extend the regression line downwards until you reach the point where it crosses the y-axis, you’ll find that the y-intercept value is negative! In fact, the regression equation shows us that the negative intercept is -114.3. Using the traditional definition for the regression constant...
