MATLAB: How to get Taxi data for New York city

big dataMATLAB

In the video here , it talks about using the New York city taxi data. It says for me to go to the website and download the data. Is there anyway to tell MATLAB to download this data directly?

What about using urlwrite?

urlwrite('https://s3.amazonaws.com/nyc-tlc/trip+data/yellow_tripdata_2016-01.csv','yellow_tripdata_2016-01.csv');

This should download the code for you.

You need to use the correct format, and the correct syntax for the time zone. (I am using R2018a, although I would be surprised if this format and syntax have changed since it was introduced in R2014b.)

Also, you do not need the datestr call.

With those changes:

t = datetime('now','TimeZone','local','Format','dd-MM-yyyy HH:mm:ss Z');  %%get the time
t.TimeZone = 'America/New_York' ;   %%define the city

produces:

t = 
    datetime
     21-08-2018 14:05:58 -0600
t = 
    datetime
     21-08-2018 16:05:58 -0400

Note: I am in the U.S. Mountain time zone (equivalent to 'America/Denver'), thus the offset.

MATLAB: Kahneman’s Taxi problem

Generate a cab of one color or the other with the appropriate probabilities.
Get the color ID response from the witness with the appropriate probability.
Record the actual cab color and the color ID response.

Iterate steps 1-3 10,000 times.

From the 10,000 iterations, select all the ones where the color ID response was blue. Say there are N of these.

Find out what proportion of those N times the actual cab color was blue.
