Density function represented by a two-column matrix in which each row corresponds to an m/z value. The first column lists the mass, and the second column lists the relative intensity of the signal at that mass. Examples Calculate and display the isotopic mass distribution of the peptide sequen...
The probability density function must therefore be rectangular, as shown in Fig. 10.4(b). Since the probability of the waveform having an amplitude in the range ±X is 1, that is, ∫-XXp(x)dx = 1the area of the rectangle in Fig. 10.4(b) is 1, and since its width is 2X, ...
The probability density function of a random variable having uniform distribution on the interval is where is an indicator function that takes value 1 on the interval and value 0 everywhere else. There are three cases: if , then if , then if , then Therefore, the cdf is More details More ...
x y, z And the basic distribution function uses the Boltzmann constant ”k” and temperature”T” with the number density to modify the normal distribution: Fermi-Dirac distribution function: The Fermi-Dirac probability density function provides the probability that an energy level is occupied by ...
The probability density function (pdf) of the chi-square distribution is y=f(x∣ν)=x(ν−2)/2e−x/22ν2Γ(ν/2), where ν is the degrees of freedom and Γ( · ) is the Gamma function. For an example, see Compute Chi-Square Distribution pdf. ...
