linstats package provides a uniform mechanism for building any supported linear model. Once built the same model can be analyzed in many ways including least-squares regression, fit and lack-of-fit statistics,
In multiple linear regression, the goal is to explain a large part of the observed variability by a set of regressors and possibly their interactions. The more variability explained, the better the prediction. Geostatistics extends this by looking at spatial correlation in the residual variability: ...
Simple Linear Regression models capture the relationship between a single attribute of a data set (called predictor or independent attribute) and an attribute of the same data set (called target or dependent attribute). Once a simple linear regression m...
As a real-world example of how to build a linear regression model, imagine you want to train a model to predict the price of houses based on the area and how old the house is. You decide to model this relationship using linear regression. The following code block shows how you can writ...
(AUC-ROC):The ROC curve plots the true-positive rate against the false-positive rate at various threshold settings. The AUC measures the entire two-dimensional area underneath the entire ROC curve. A model with perfect predictions has an AUC of 1.0, while a model that makes random guesses ...

This is the core of our model where learning happens. It consists of 10 neurons and uses the ReLU (Rectified Linear Unit) activation function, which introduces non-linearity to help the model learn complex patterns in the data. Output layer:The output layer predicts whether a transaction is ...
It supports multiple hidden layers with a specifiable number of nodes. Each layer can have one of several activation functions. The output layer is a single numeric or binary categorical target. The output layer can have any of the activation functions. It has the linear activation function ...
2.5 A Statistical Approach to Optimize Mixture Designs In multiple linear regression, the prediction model can be considered as an equation expressing the relationship between dependent and independent variables. In this study, the dependent variables were slump and slump flow, whereas the independent va...
