I attached an image file of excel data in which the problem is to predict the value of u by using any mathematical method.so, please share me the procedure or method to be followed to solve the problem.thank you in advance.
@Narvesh If your data is continuous (as it seems) then you can either use median or mean value for imputing missing data (i.e. u). For median replacement, you can use Excel StatTools package by James Gaskin. You can download the package from the link below.👇🏼
