Gaussian csdn
WebThe Gaussian cumulative distribution function (cdf). This is the integral of pdf(t,m,s) from -infinity to x over t: int_{-infty}^x exp( -0.5 ( (t-m)/s )**2 )/sqrt(2*pi*s**2) dt. Only the first argument is mandatory, the other two are optional.

WebI am reading Gaussian Distribution from a machine learning book. It states that - We shall determine values for the unknown parameters $\mu$ and $\sigma^2$ in the Gaussian by maximizing the likelihood function. In practice, it is more convenient to maximize the log of the likelihood function. Because the logarithm is monotonically increasing ...
