Question 2 0 pts In some cognitive modeling applications, it is desirable to fit the model to individual subject data. In this case, each individual would be associated with its own

set of parameters. However, if there are only few observations for each individual, it might be challenging to get good estimates for parameters such as the learning rate parameter c. One solution is to share some parameters across individuals. For example, all individuals have the same parameter c but each individual has their own parameters a and u. Apply this modeling approach to the data from users 48567, 144155 and 30222 and modify your least-squares fitting code accordingly. Note that you will now have (3 x 2) + 1 = 7 parameters to fit. Upload the code you created and report (in your code) what parameter values you found. [1 points max]
