Program 3dRegAna was developed to provide multiple linear regression analysis across AFNI 3d datasets. For each input dataset, the user must enter the quantitative level that applies for each of the independent (predictor) variables. The user also speci–es which variables are to appear in the full linear regression model, as well as a simpler ...

The scatter plot shown in Figure 3 indicates that a simple linear regression model might be appropriate for our project data. In particular, the fitted regression model is E est = 585.7 + 15.124 × FP (Model 1) where E est is the estimated development hours and FP is the size in function points. The

We propose protocols that se-curely compute a linear regression model over two separate datasets according to our de nition (we later show that our solution can be extended to the case of multiple parties). Our results are information-theoretically secure ...

Having developed these two different models (linear regression we needed some way of comparing their results. For this project, we implemented two such methods. In the first method, we map the results from linear regression into the five bucket classes from logistic regress ion. To do this, we take the real

When there are more than one independent variables in the model, then the linear model is termed as the multiple linear regression model.

This statement uses pyplot to create a scatter plot of the two datasets. The stats module’s lineregress method is used to run a linear regression on the two datasets. The slope and y-intercept from the linear regression are used to calculate the y-values predicted by the regression. Note that xData is an array and math operators are
