Probability - Linear Regression
显示 更早的评论
Can I get some help for this question?
Below is my attempt
x=[1 3 5 9 11 13];
y=[22 51 127 202 227 248 252];
scatter(x,y)
That is the furthest I can go. Any help would be appretiated. :)

start with completing your x data - the seven is missing. Then begin to read about least squares curve fitting. To do this you should learn how to code your function in Matlab using a function handle.

I don’t know if you have the Optimization Toolbox or the Statistics and Machine Learning Toolbox, both of which have nonlinear regression functions. One function everyone has is fminsearch (link).
To use it, you will need to optimise a function of the form:
fcn = @(b) norm(y - Hfcn(b,t));
where ‘Hfcn’ is the function you will write for ‘H(t)’, ‘b’ is the parameter vector, and ‘t’ and ‘y’ are the respective data vectors.
I leave the rest to you!
EDIT —
Your ‘t’ vector is also missing a value. It should be:
t=[1 3 5 7 9 11 13];
I discovered that when I actually did the regression.

As always, my pleasure.
My polar bear thanks you for the compliment!
