Calculate parameters for uniformly distributed values.
procedure UniformFit(const X: TVec; out low: double; out high: double; var PCILow: TTwoElmReal; var PCIHigh: TTwoElmReal; Alpha: double = 0.05); overload;
Parameters |
Description |
X |
Stores data which is assumed to be uniformly distributed. |
low |
Return uniform distribution parameter estimator Low. |
high |
Return uniform distribution parameter estimator High. |
PCILow |
Low (1-Alpha)*100 percent confidence interval. |
PCIHigh |
High (1-Alpha)*100 percent confidence interval. |
Alpha |
Confidence interval percentage. |
RandomUniform, UniformStat
The following example generates 100 random uniformly distributed values and then uses UniformFit routine to extract used Low and High parameters
Uses MtxExpr, Math387, Statistics; procedure Example; var vec1: Vector; resLow, resHigh : double; CILow,CIHigh: TTwoElmReal; begin // first, generate 1000 randomly Uniformly distributed // numbers with parameters Low=1.5 and High =2.2 vec1.Size(1000); RandomUniform(1.5,2.2,vec1); // Now extract the Low,High and their 95% confidence intervals. UniformFit(vec1,resLow,resHigh,CILow,CIHigh); end;
