Error matrix based on samples

WebA frame is a vector or a matrix (multichannel signal) of buffered samples of consecutive times stacked together. Both frames and samples can be matrices, but in frames the first dimension is parsed as a time domain and the second dimension is parsed as channels. ...

Websample) and 500 columns (one for each sampled value, to match the original sample size). We will then use apply() to apply mean() to each row of the matrix. This approach di ers from the example in the author R guide that uses a for loop, but we can show this approach later as well. First create a large matrix to store all of the samples. B=1000 In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value. MSE is a risk function, corresponding to the expected value of the squared error loss. The fact that MSE is almost always strictly positive (and not zero) is because of randomness or beca…
