I have daily rain data of a particuler area for past 20 years i.e 20 vecotrs of 1*365. My supervisour asked to calculate its pdf(probability density function) and use this function to calculate rain on a particuler day. But, I am unable to code this. I would highly appriciate you...
x=linspace(ymin,ymax,20);%将最大最小区间分成20个等分点(19等分),然后分别计算各个区间的个数 yy=hist(y,x);%计算各个区间的个数 yy=yy/length(y);%计算各个区间的个数 bar(x,yy);%画出概率密度分布图 hold on; plot (x,yy,'LineWidth',2); s=0; xlabel('x','FontSize',20); ylabel('...
This MATLAB function returns the probability density function (pdf) for the one-parameter distribution family specified by name and the distribution parameter A, evaluated at the values in x.
y= wblpdf(x)returns the probability density function (pdf) of the Weibull distribution with unit parameters, evaluated at the values inx. example y= wblpdf(x,a)returns the pdf of the Weibull distribution with scale parameteraand unit shape, evaluated at the values inx. This is equivalent to...
y= exppdf(x)returns the probability density function (pdf) of the standard exponential distribution, evaluated at the values inx. example y= exppdf(x,mu)returns the pdf of the exponential distribution with meanmu, evaluated at the values inx. ...
You can calculate the support for the Pearson distribution pdf usingcoefs. For more information, seeProbability Density FunctionandSupport.
