dotnetCHARTING Namespace > ForecastEngine Class > TrendLine Method : TrendLine(String,Series,Series,Int32) Method
The name of the series which will be displayed on the chart, i.e. its label.
A statistical series.
A series wich contains the standard deviations of the given data point.
When this parameter is 0 the standard deviation will not be considered.
TrendLine(String,Series,Series,Int32) Method
Given a set of data points x[0..ndata-1],y[0..ndata-1] with individual standard deviations sig[0..ndata-1], fit them to a straight line y = a + bx by minimizing ¥ö2. Returned are a,b and their respective probable uncertainties siga and sigb, the chi-square chi2, and the goodness-of-fit probability q (that the fit would have ¥ö2 this large or larger). If mwt=0 on input, then the standard deviations are assumed to be unavailable: q is returned as 1.0 and the normalization of chi2 is to unit standard deviation on all points.
