sample.curve |
Provide the number of observations to simulate curvature (default is 1000) |
ylab |
Variable response name (Accepts the expression() function) |
xlab |
treatments name (Accepts the expression() function) |
theme |
ggplot2 theme (default is theme_classic()) |
error |

legend.position |
legend position (default is "top") |
r2 |
coefficient of determination of the mean or all values (default is all) |
point |

The model analogous to the three-parameter Gaussian is:
y = d \times e^{-b((x-e)^2)}
The model analogous to the three-parameter Gaussian is:
y = d \times c+(d-c)*e^{-b((x-e)^2)}
The function returns a list containing the coefficients and their respective values of p; statistical parameters such as AIC, BIC, pseudo-R2, RMSE (root mean square error); largest and smallest estimated value and the graph using ggplot2 with the equation automatically.
