Hello,
I want to ask that when we do the linear fitting in the origin we are getting the option of the standard error with intercept and slope. How can we get the standard deviation of intercept and slope?

What is the best method to find linear trend when our data also contains data gaps? Any standard method is there?

Hi,

Actually, when do linear fitting, the standard deviation of parameters is the standard error of those parameters which will be output by default.

About the linear trend, can you give us more details about the data gaps?

Thanks,
Shirley

Hello,
Thanks for your reply.

Suppose we are using the daily average data or monthly average data of temperature and if we have 1-2 month gap in the data for few years. In that case which method we should use to determine trend. What is the most scientifically accepted method.


Thanks
Gracy
