Gompertz curve modelling using NLIN PROC

[samkelomotsa]

I want to use the Gompertz curve model to develop a growth curve and also get the analysis components. the model that i want to use is :

BWt = BW0 * exp*(L/K(1 - exp(-Kt))). 

The equation includes parameters such as BWt (recorded body weight at age t), BW0 (estimated weight at hatching), L (initial specific growth rate), and K (maturation rate or exponential factor of decay of the specific growth rate).

how can i go about developing the code.

line in the data stands from the animal breed in other terms. this is a sample of the data set. otherwise, the data set is huge.

LINE	BW0	WEEK	BWT
F01	39.0	2	153.6
F01	39.0	2	128.4
F01	37.0	2	143.2
F01	31.8	2	107.0
F01	32.6	2	144.6
F01	32.4	2	117.2
F01	35.6	2	154.2
F01	37.4	2	.
F01	33.4	2	66.6
F01	32.0	2	92.6
F01	37.6	2	154.0
F01	34.8	2	125.6
F01	34.4	2	113.8
F01	37.2	2	146.8
