What is convergence of probability?

"Convergence in probability" is a technical term in relation to a series of random variables. Not clear whether this was your question though, I suggest providing more context.


What factors determines the region of convergence of a z transform?

The region of convergence (ROC) of x(z) is the set of all values of z for which x(z) attains a finite value.


Why can a power series converge conditionally for at most two points?

A power series converges conditionally only at its center of convergence and possibly at one endpoint of its interval of convergence. This is because conditional convergence implies that the series converges but does not converge absolutely. It can only have limited points of convergence, as it cannot oscillate between converging and diverging without becoming divergent overall. Thus, at most two points can exhibit this behavior: the center and one endpoint.


What is the utility of 'convergence rate' in numerical computing?

The convergence rate is a measure of how quickly the calculations become close to the value being calculated. Alternatively, how quickly the error becomes smaller.The convergence rate is a measure of how quickly the calculations become close to the value being calculated.

What is absolute convergence for an alternating series?

Absolute convergence for an alternating series refers to the situation where the series formed by taking the absolute values of its terms converges. Specifically, if an alternating series takes the form ( \sum (-1)^n a_n ), where ( a_n ) are positive terms, it is said to be absolutely convergent if the series ( \sum a_n ) converges. Absolute convergence implies convergence of the original alternating series; hence, if an alternating series is absolutely convergent, it is also convergent in the regular sense.
