QSAR Analysis

Question 1

What does the R2 value mean?

Answer 1

This indicates the correlation between predicted and observed activity.
If it is a high number close to one: This indicates a very strong correlation between predicted and observed activity. Or This means % of the variation in biological activity is explained by the model.

Question 3

What does the R^2 mean?

Answer 3

indicates the correlation between predicted and observed activity.
The percentage of the variation in biological activity is explained by the model.

Question 4

What does the S value mean?

Answer 4

How much the predicted values deviate from the experimental values.

Question 5

what does the F-statistic indicate?

Answer 5

A very large F value indicates the regression is highly statistically significant and unlikely to arise from random variation.
