Ten samples are available, i.e., -1.3499, 3.0349, 0.7254, -0.0631, 0.7147, -0.2050, -0.1241, 1.4897, 1.4090, 1.4172, to fit a distribution using the Kernel Density Function. If a Gaussian Kernel Function is selected with a bandwidth of 0.7693, estimate the PDF (probability density function) values at following sample locations: -3.0, 1.5, and 4.0.
