QUESTION
I would Like to get a count of the number of days for which (VZ) stock return is larger than the stock index return (INX)
I already calculated the return using the pct_change function. Now I want to get the number of days VZ is larger than INX. I don't know how to go about this.
ANSWER
Answered 2022-Mar-31 at 23:53To do this you can check which times the "VZ" value is higher than the "INX" value using a column operation, and get the sum of the output:

I am experiencing an issue on my local system, which I cannot figure out to solve. I am using Bazel and it looks like the Bazel server process is being blocked by some Mac OS security setting from opening ports.

Answered 2021-Nov-10 at 21:08As embarrassing as it is, restarting the Mac followed by an sudo rm -rf /private/var/tmp/_bazel_me (just to be sure) fixed it.
QUESTION
fmt.Print("Enter valid nbd: ")
reader := bufio.NewReader(os.Stdin)
input, err := reader.ReadString('\n')
if err != nil {
fmt.Println("An error occured while reading input. Please try again", err)
return
}
input = strings.TrimSuffix(input, "\n")
cmd = exec.Command("/bin/bash", "-c", "qemu-nbd -c /dev/", input, "/tmp/var/lib/vz/images/201/vm-201-disk-0.qcow2")
cmd.Run()
cmd = exec.Command("/bin/bash", "-c", "mount /dev/", input, "p1 /mnt")
cmd.Run()
ANSWER
Answered 2022-Mar-16 at 11:17It is possible. Code is correct, you can use cmd.String to print executed command. There is most likely error during execution.
I would recommend to use cmd.Output() and cmd.StderrPipe() for debugging.
QUESTION
I have an issue with a simple struct creation with generic type, as follows:
...ANSWER
Answered 2022-Feb-26 at 13:48When working with type parameters, the only thing that Rust assumes about the type is that it is Sized. Any other constraints on the type parameter must be explicitly written out.
Also, Rust's default move semantics mean that a value can have only a single owner, and that once a value is "moved out of" a place, it is no longer valid there. You can opt out of this behaviour by implementing Copy, though this is only valid for types that can be meaningfully memcpy-ed, so many things can't use this (anything with a Drop impl, &mut T, and more). TLDR, it's a fairly restrictive bound to put on an API.
The much more general case is Clone, which is a supertrait of Copy (which means: any T that implements Copy, also implements Clone). The difference is that Clone is potentially an expensive operation, potentially requiring heap allocations, and must be explicitly called via Clone::clone, but the tradeoff is that it is far more widely applicable.
So I'd suggest rewriting your code as follows:

QUESTION
I have a 3-dimensional embedded time series. How can I find the points/coordinates (x, y, z) where the 3d matrix of the time series intersects an arbitrary hyperplane. The problem is I don't have an equation for my embedded time series. Do I either find the closest points to the hyperplane and project them onto my hyperplane or do I find where one point crosses onto the other side to another point and then find the equation of that line and plug in my z-value to find the (x, y) coords? My plot looks like this:
Here's my current code for replicability:
...ANSWER
Answered 2022-Feb-01 at 17:53So here's my solution to find the intersection of points that pass from above to below an arbitrary hyperplane. In my code, after I have created the taken matrix, here's my new implementation:

QUESTION
I am solving differential equations numerically using solve_ivp in order to integrate positions and velocities from an initial condition. This is straighfoward in Python and easy to do. But I am also calculating the partials of final positions and velocities with respect to the initial positions/velocities and time using numdifftools.Jacobian. This I have more trouble mastering. Let me explain.
I have a set of differential equations (see rhs_CR3BP function) that I numerically integrate over a timespan [0,T] using the Python solver solve_ivp given an initial state vector X_0 at t=0 (position and velocity). At the end of the integration, I have all the state vectors from t=0 to t=T stored in solve_ivp.y, with the final state vector X_f at t=T stored in solve_ivp.y[:, -1].
I am trying to compute numerically partial derivatives of the final state vector X_f with respect to the initial state vector X_0 and period T, which are in fact the components of a Jacobian matrix.
Consider the following vector:

Answered 2022-Jan-12 at 04:05Replacing nd.Jacobian(f, method='complex') with nd.Jacobian(f, method='central') yields the following matrix:
