Straight up deserve a subscribe and a like. Thank you so much good sir. I wish you the very best and I hope you live a long and fulfilling life. God bless.
You could break up the data set and then perform three separate regressions. Here is information on nonlinear regression: apmonitor.com/che263/index.php/Main/MatlabDataRegression
Respected viewer I am having a system for which I have to regress 3 unknown parameters and also the function value(temperature dependent) basically NRTL model . May I please get some help.
+Usama Khan I'm glad that this video helped. There are many others on Python and MATLAB at the open course on Computational Tools for Engineers: apmonitor.com/che263
Here is information on showing the prediction band and 95% confidence interval. uolab.groups.et.byu.net/files/Statistics%20Review%20Harding.pptx See slide 9 in particular.
thanks a lot professor for the nice video. but, I want to ask something about regression. does regression has a strong correlation with numerical method, and is numerical method distinctively different with optimization? or even optimization is the part of numerical method? thank you.
Most regression methods use a numerical approach. Here is more information: apmonitor.com/che263/index.php/Main/PythonDataRegression (Python) or apmonitor.com/che263/index.php/Main/MatlabDataRegression (MATLAB)
Here are additional resources for regression: apmonitor.com/che263/index.php/Main/MatlabDataRegression unfortunately I can't help with all user specific questions but I can point to resources. Maybe you could post to StackOverflow or to Mathworks to get a community of users to help with your problem as well.
+Qurrat Hyder, all videos are available in 1080p (1960px x 1080px). TH-cam automatically scales back the video resolution for slow Internet connections. I'd recommend switching to 1080p in the options at the bottom right and wait for the video to load. Let me know if this does not fix the blurry issue.

how to find the multivariate regression equation for a regression model trained in regression toolbox?
Here is more information on regression: apmonitor.com/pds/index.php/Main/RegressionOverview
what is SStotal?
Total Sum of Squares
Thanks a lot sir for this awesome tutorial!
Pls also make a video on how to calculate the standard error of estimate in MATLAB.
I don’t have it in Matlab, but here is something similar in Python: apmonitor.com/che263/index.php/Main/PythonRegressionStatistics
How would I go about adding a linear, power, and exponential curve to fit each third of a data set?
You could break up the data set and then perform three separate regressions. Here is information on nonlinear regression: apmonitor.com/che263/index.php/Main/MatlabDataRegression
How can we generate quadratic equation from given data
The coefficients of the quadratic equation are available with disp(p2) at 2:40 in the video.
Do you have any Matlab based source code for multivariate linear regression?
Yes, here are some tutorials: apmonitor.com/do

Thanks for the tutorial. I have similar data points along with standard deviation (errorbar). So how do I show the deviation of slope ?

really good tutorial...thanks
thanks a lot professor for the nice video. but, I want to ask something about regression. does regression has a strong correlation with numerical method, and is numerical method distinctively different with optimization? or even optimization is the part of numerical method? thank you.
Regression is a type of optimization where parameters are adjusted to minimize a measure of how close the prediction aligns to data.
Most regression methods use a numerical approach. Here is more information: apmonitor.com/che263/index.php/Main/PythonDataRegression (Python) or apmonitor.com/che263/index.php/Main/MatlabDataRegression (MATLAB)
Hello Sir, How do we calculate correlation for polynomials...?
Can u help me dude ? I have a problem with my matlab question

Awesome thank you :)
thank you ^^
i cant see anything blur
