Calculating R^2 for a nonlinear least squares fit - Stack Overflow
Webb26 jan. 2013 · As a direct answer to the question asked (rather than argue that R2/pseudo R2 aren't useful) the nagelkerke function in the rcompanion package will report various pseudo R2 values for nonlinear least square (nls) models as proposed by McFadden, Cox and Snell, and Nagelkerke, e.g. Pseudo-R-squared values are used when the outcome variable is nominal or ordinal such that the coefficient of determination R cannot be applied as a measure for goodness of fit. In linear regression, the squared multiple correlation, R is used to assess goodness of fit as it represents the proportion of variance … Visa mer R L is given by Cohen: $${\displaystyle R_{\text{L}}^{2}={\frac {D_{\text{null}}-D_{\text{fitted}}}{D_{\text{null}}}}.}$$ This is the most analogous index to the squared multiple … Visa mer R McF is defined as $${\displaystyle R_{\text{McF}}^{2}=1-{\frac {\ln(L_{M})}{\ln(L_{0})}},}$$ and is preferred over … Visa mer However, Allison now prefers R T which is a relatively new measure developed by Tjur. It can be calculated in two steps: 1. For … Visa mer R CS is an alternative index of goodness of fit related to the R value from linear regression. It is given by: Visa mer R N, proposed by Nico Nagelkerke in a highly cited Biometrika paper, provides a correction to the Cox and Snell R so that the maximum value is equal to 1. Nevertheless, the Cox and Snell and likelihood ratio R s show greater agreement with each … Visa mer A word of caution is in order when interpreting pseudo-R statistics. The reason these indices of fit are referred to as pseudo R is that they do not represent the proportionate reduction in error as the R in linear regression does.
