Mathematical Simulations, Models & Worksheets
This Mathcad 11 worksheet demonstrates the principal component analysis of multidimensional data. You can enter multidimensional data, calculate the principal components, discard the least significant components and reconstruct the simplified data set.
This Mathcad 11 worksheet contains algorithms that define the structure of linear, cubic and parabolic splines.
In this Mathcad 11 worksheet, I've generated a random data set according to a one-parameter Weibull distribution, and then backsolved for the shape parameter by maximising the likelihood function. I've then plotted the predicted distribution against a histogram of the data
This Mathcad 11 worksheet demonstrates how to solve systems of linear equations. It also demontrates the least-squares solution to an overdetermined system, and the minimum-norm solution of an underdetermined system.
