Texas Election Returns

This is a set of functions that allows to test the weak form market efficiency and thus the predictability of the time series returns through various tests: direct and indirect test.The direct tests are the two versions (individual and joint)of the variance ratio of Lo and MacKinlay (1988).The...

This is a function that returns a string vector containing the expiration dates of options when a serial date vector is given. Also returns the index of the expiration fridays in the serial date vectors.

Function takes a picture as an argument (suitably should contain only one object whose centroid is to be obtained) and returns the x and y coordinates of its centroid.
