Functions and values

Function or value	Description
`fit xData yData` Full Usage: `fit xData yData` Parameters: xData : `Vector<float>` - vector of x values yData : `Vector<float>` - vector of y values Returns: `Coefficients` Slope of the regression line through the origin	Calculates the slope of a regression line through the origin xData : `Vector<float>` vector of x values yData : `Vector<float>` vector of y values Returns: `Coefficients` Slope of the regression line through the origin Example `// e.g. days since a certain event let xData = vector [\|0.;1.;2.;3.;4.;5.;\|] // some measured feature, that theoretically is zero at day 0 let yData = vector [\|1.;5.;9.;13.;17.;18.;\|] // Estimate the slope of the regression line. let coefficients = LinearRegression.OLS.Linear.RTO.fit xData yData` val xData: obj val yData: obj val coefficients: obj
`fitOfVector xData yData` Full Usage: `fitOfVector xData yData` Parameters: xData : `Vector<float>` - vector of x values yData : `Vector<float>` - vector of y values Returns: `Coefficients` Slope of the regression line through the origin	Calculates the slope of a regression line through the origin xData : `Vector<float>` vector of x values yData : `Vector<float>` vector of y values Returns: `Coefficients` Slope of the regression line through the origin Example `// e.g. days since a certain event let xData = vector [\|0.;1.;2.;3.;4.;5.;\|] // some measured feature, that theoretically is zero at day 0 let yData = vector [\|1.;5.;9.;13.;17.;18.;\|] // Estimate the slope of the regression line. let coefficients = LinearRegression.OLS.Linear.fit xData yData` val xData: obj val yData: obj val coefficients: obj
`predict coef x` Full Usage: `predict coef x` Parameters: coef : `Coefficients` - The functions slope x : `float` - x value of which the corresponding y value should be predicted Returns: `float` predicted y value	Predicts the y value for a given slope and x value (intercept=0) coef : `Coefficients` The functions slope x : `float` x value of which the corresponding y value should be predicted Returns: `float` predicted y value Example `let mySlope = 17.8 // Returns predicted y value at x=6 using a line with intercept=0 and slope=17.8 LinearRegression.OLS.Linear.RTO.predict mySlope 6.` val mySlope: float
`predictFunc coef x` Full Usage: `predictFunc coef x` Parameters: coef : `Coefficients` - The functions slope x : `float` - x value of which the corresponding y value should be predicted Returns: `float` Function that takes a x value and returns the predicted y value	Returns the regression function of a line through the origin coef : `Coefficients` The functions slope x : `float` x value of which the corresponding y value should be predicted Returns: `float` Function that takes a x value and returns the predicted y value Example `let mySlope = 17.8 // get the fitting function that fits through the origin let myF = LinearRegression.OLS.Linear.RTO.predictFunc mySlope // Returns predicted y value at x=6 using a line with intercept=0 and slope=17.8 myF 6.` val mySlope: float val myF: (float -> obj)
