Instance members

Instance member	Description
`this.Add` Full Usage: `this.Add` Parameters: x : `float` - The x value of the data point. y : `float` - The y value of the data point.	Adds a data point to the regression. x : `float` The x value of the data point. y : `float` The y value of the data point.
`this.AddRange` Full Usage: `this.AddRange` Parameters: values : `IEnumerable<float * float>` - The data points to add.	Adds data points to the statistics. values : `IEnumerable<float * float>` The data points to add.
`this.GetA0` Full Usage: `this.GetA0` Returns: `float` The intercept value or NaN if not enough data points are entered.	Gets the intercept value of the regression. Returns NaN if not enough data points entered. Returns: `float` The intercept value or NaN if not enough data points are entered.
`this.GetA1` Full Usage: `this.GetA1` Returns: `float` The slope value or NaN if not enough data points are entered.	Gets the slope value of the regression. Returns NaN if not enough data points entered. Returns: `float` The slope value or NaN if not enough data points are entered.
`this.GetA2` Full Usage: `this.GetA2` Returns: `float` The slope value or NaN if not enough data points are entered.	Gets the quadratic parameter of the regression. Returns NaN if not enough data points entered. Returns: `float` The slope value or NaN if not enough data points are entered.
`this.GetDeterminant` Full Usage: `this.GetDeterminant` Returns: `float` The determinant of the regression.	Returns the determinant of regression. If zero, not enough data points have been entered. Returns: `float` The determinant of the regression.
`this.GetYOfX` Full Usage: `this.GetYOfX` Parameters: x : `float` - The x value. Returns: `float` The y value at the value x.	Gets the y value for a given x value. Note that in every call of this function the polynomial coefficients a0, a2, and a1 are calculated again. For repeated calls, better use QuickQuadraticRegression.GetYOfXFunction, but note that this function represents the state of the regression at the time of this call. x : `float` The x value. Returns: `float` The y value at the value x.
`this.GetYOfXFunction` Full Usage: `this.GetYOfXFunction` Returns: `Func<float, float>` A function to calculate y in dependence of x.	Returns a function to calculate y in dependence of x. Please note note that the returned function represents the state of the regression at the time of the call, i.e. subsequent additions of data does not change the function. Returns: `Func<float, float>` A function to calculate y in dependence of x.
