Exponentially Modified Gaussian minpack.lm objective function — emgGaussian_minpack.lm

Exponentially Modified Gaussian (EMG) minpack.lm objective function, calculates residuals using the EMG Peak Shape

emgGaussian_minpack.lm_objectiveFun(params, observed, xx)

Arguments

params: (list) exponentially modified gaussian parameters (params$gamma, params$center, params$sigma, params$amplitude)
observed: (numeric) observed y value at xx
xx: (numeric) value at which to evalute the exponentially modified gaussian

difference between observed and expected exponentially modified gaussian value evaluated at xx
