In this post, I show how to interpret regression models that have significant independent variables but a low R-squared. To do this, I’ll compare regression models with low and high R-squared values so you can really grasp the similarities and differences and what it all means. Related pos...
R-squaredis a goodness-of-fit measure for linear regression models. This statistic indicates the percentage of the variance in the dependent variable that the independent variables explain collectively. R-squared measures the strength of the relationship between your model and the dependent variable on...
multinomial logistic regression (MLR)practice-based researchstatistical techniquesThe purpose of this article is to explain how to conduct a multinomial logistic regression (MLR) to increase its usage among social work researchers. A challenge for social work researchers carrying out practice-based ...
In the section, Test Procedure in Stata, we illustrate the Stata procedure required to perform multiple regression assuming that no assumptions have been violated. First, we set out the example we use to explain the multiple regression procedure in Stata....

Now, let me briefly explain how that works and how softmax regression differs from logistic regression. I have a more detailed explanation on logistic regression here:LogisticRegression - mlxtend, but let me re-use one of the figures to make things more clear: ...
After you import the function, you simply call it asLogisticRegression(). Inside the parenthesis, there are a few optional parameters that you can use to control how the function behaves. I’ll explain those in a section below. When we call the LogisticRegression function, we commonly save ...

Part 1. What is Excel Linear Regression? In Excel, Linear Regression is a statistical tool and a built-in function used to find the best-fitting straight line that describes the linear relationship between two or more variables. It is commonly employed for predictive modeling and analyzing the ...
Multioutput regression are regression problems that involve predicting two or more numerical values given an input example. An example might be to predict a coordinate given an input, e.g. predicting x and y values. Another example would be multi-step time series forecasting that involves predicti...
