fitSingleSigmoid {NPARC} | R Documentation

## Fit sigmoid model

### Description

Fit sigmoid model

### Usage

    fitSingleSigmoid(x, y, start = c(Pl = 0, a = 550, b = 10))

### Arguments

`x` | numeric vector of the independent variables (typically temperature)
`y` | numeric vector of the dependent variables (typically relative abundance measurements)
`start` | numeric vector of start parameters for the melting curve equation

### Details

Fits the following function to the data: y = (1 - Pl) / (1+exp((b - a/x))) + Pl

### Value

model summary of type "nls"

### Examples

    data(stauro_TPP_data_tidy)
    stk4 <- dplyr::filter(stauro_TPP_data_tidy, grepl("STK4", uniqueID))
    fitSingleSigmoid(stk4$temperature, stk4$relAbundance)
