Curve fitting in origin: explained step by step

[@PeoplesCourt_07]

Hello sir, how can I fit user defined model or exponential decay for current vs time in chronoamperometric techniques please I need your help in this regards

[@SAYPhysics]

To do fitting with a customized equation, I have another tutorial which will help you to understand. Thanks kzbin.info/www/bejne/jJqslXiiodpopqM

[@atiqurrahman8470]

hello, can you please let me know to converte the data with five interval difference into a data with unit interval difference. thanks

[@SAYPhysics]

To convert your data from a five-interval difference to a unit interval difference, you could try plotting your data and then fitting it to interpolate the values at each unit interval. This way, you'll have a smoother dataset with the desired interval. Thanks

Hello sir, how can I fit BCS model equation of heat capacity

[@SAYPhysics]

Thanks for your question! You can fit the BCS model equation for heat capacity in Origin by customizing the fitting function. If the BCS equation isn’t pre-defined in Origin, you can manually input it and perform the fit. I recommend watching my video on how to customize fitting equations in Origin for a step-by-step guide. It will help you set up the BCS model specifically. You can find the video at kzbin.info/www/bejne/jJqslXiiodpopqM

@@SAYPhysics I tried fitting it but it's gives me a value of 1.83E-295 for any value of X, my aim to fit C/T vs T^(2) and be able to obtain T_c from the BCS model fit.

[@SAYPhysics]

@mlungisimasondo3613 it's definitely not a valid value. Try refining your parameters. Thanks

Hello sir, how can I fit the conversion Rate graph by the Friedman method, please I need your help in this regards

[@SAYPhysics]

I've no idea about it dear. Thanks

[@ganesharya3512]

can i do curve fitting multiple independent variables on origin

[@SAYPhysics]

Yes, see my advanced fitting video on 'Curve fitting of multiple peaks in origin: tips and tricks' kzbin.info/www/bejne/jJqslXiiodpopqM

[@arsalanadil14912]

This kind of fitting is little sophisticated but it required more practiced for good fitting

[@SAYPhysics]

You’re right. Step by step follow up makes it easy. Thanks

[@aimersclasses2.0]

Can u reply quickly if possible plz Why we do fitting?/I mean what do we do by fitting curve

[@SAYPhysics]

Fitting provides a trend to our scattered data and help in deducing some parameters. Thanks

[@aimersclasses2.0]

@@SAYPhysics sir can you plz elaborate if you have time??🙏🙏

[@aimersclasses2.0]

Sir can you plz reply ,,ki kya h ye fitting ,,kyun krte hai fitting??? Plz sir 🙏🙏🙏 Kl mera viva h

[@SAYPhysics]

I have already responded to you. In urdu, muntashir data points kay andhar kia trend hai ya aik haas trend kay kia parameters hai, us kay liay hum fitting kartay hain. Thanks

[@aimersclasses2.0]

@@SAYPhysics thank you sir

[@sikanderhayat7269]

i think u can do it better way using origion

[@SAYPhysics]

I have multiple videos in this playlists. Each of them is addressing different aspects. Thanks
