comment Different Central Tendency Measures for Describing Groups or Individuals
I agree with always using the median. I couldn't find any questions similar to mine about mixing different statistics. Intuitively, it seems wrong but given it was per user I thought it would be best to provide the best statistic for each user. That was my thought process.

comment fitcdiscr function in MatLab
I appreciate the offer, but I really needed to solve the problem in MatLab. I ended up finding other, more explicit, solutions. I'm still very surprised`fitcdiscr` doesn't work as the documentation suggests.

comment Least squares linear classifier in matlab
@3lectrologos, one last question. Why does a = -z(3)/z(2) and b = - (z(1)/z(2)) in the final linear equation? lsqlin returns a vector with n elements, the same number of variables/columns in the C matrix. So how would we construct the linear equation with four, five, etc. variables?

comment fitcdiscr function in MatLab
I'm having a similar issue with fitcdiscr. I have the most basic example data and I'm following the MatLab doc with no success. I think something is either wrong with the function or docs. Most likely the latter.

@3lectrologos, if you have a training set, can you put the correct class values in the third column? I appreciate the help.

comment Least squares linear classifier in matlab
@3lectrologos, how does the extra column impact the linear separator found? When I set the extra column values to 0 instead of 1 I get a better solution. And even more so when half of the extra column values are -1 and the other 0.

comment How do I get overall Facebook page video view counts by month?
It's not that other period values don't work. The table shows that 'lifetime' is the only period value that video requests will take. So, it looks like you would need to store the values locally to compute monthly metrics.
