The analysis class

The interface of the class analysis is :

   interface analysis 
   {
     analysis(histogram* h);           // taking histogram to be analyzed
     virtual ~analysis();   

     screen* format(char* p,char* options = "");
     screen* format(widget* w,char* p,char* options = "");
 
     double confidence(char* options = ""); // confidence interval of mean
     double confidence(histogram* h,char* options = ""); // difference

     double covariance(histogram* h2);  // covariance h and h2
     double correlation(histogram* h2)  // correlation h and h2
   
     double chisquaretest(double* expected); // chi-square test
   
     double linear();                    // linear fit, return chi-square
     double linear(double a,double b);   
     double quadratic();                 // quadratic fit, return chi-square
     double quadratic(double a,double b,double c);
   
     double uniform();                   // uniform fit, return chi-square
     double uniform(double a,double b);     
     double exponential();               // exponential fit, return chi-square
     double exponential(double a);     
               .
               .
               .
     double laplace();                   // laplace fit, return chi-square
     double laplace(double a); 
   
     int behavior(histogram* h,int n);   // report behavior, gets buffer size
   };

The analysis class provides a format method to create the output screen. If this function is not invoked the screen is by default toplevel. The format method takes the following options

• -foreground (color) - default black
• -background (color) - default grey
• -plot (color) - default red (for curve fitting)
• -width (int) - default 400
• -height (int) - default 100

The method behavior can be used to analyze the behavior of the simulation, for example when detecting the steady state. It generates a report on the moving average of the given histogram.
