### Find the Mean Error of Irregularly Sampled Data

There are different metrics of error you can use, one of which is mean squared error: $$MSE=\sum_{i=1}^n (y_i-\hat y_i)^2$$ Another one is mean absolute error, given by MAE=\sum_{i=1}^n|y_i-\hat y_i|...

### Probability of sampling at least one member of each class

Consider for example $6$ samples, $2$ of which are blue (B1 and B2), $2$ of which are green (G1 and G2), and $2$ red (R1 and R2). Then we want to pick at least one sample from each color with $n=4$ ...

### Bounding linear interpolation error for bandlimited functions

Without more information the bound is infinite. Now, if the signal is bounded as well, you can use this inequality to get a bound on the derivative of the signal: https://dsp.stackexchange.com/...
