The normal distribution is one of the most important distributions in statistics. We next explore characteristics of this distribution.
It is very useful for us
Dear Dr. Charles,
Thank you for your helpful website. it is another school.
I have posted below message to your attention.
could you advise me how I can linearize, normalize and homogeneize my data without alterating them?
I am currently developing a model based on Neural Networks.
Performance analyzes were successfully done but doing graphical residual analysis, I observed the trend to be a bit linear as shown below. while performing residual analysis, I noticed that Percentile Vs residual isnot linear, even Residual Vs predicted is lineary and not randomly distributed.
I tried a lot of method of data transformation method but I did not succeed. When I transform other data set, it works. It is just my dataset which is kind difficult for me. Can someone show me how to transform my data to achieve linearity? Below are my data:

When I created a chart of the observed data vs the predicted data it was (probably not surprisingly) almost a perfect straight line (except for the first few data elements which were slightly off). What more linearity do you need?
kindly wish to understand the process of setting the real statistic park for all regression scalculations
Sorry, but I don’t understand your question.
