xmu_check_variance: Check the minimum variance in data frame

Description

Check that each variable exceeds a minimum variance and all are on compatible scales. Let the user know what to do if not.

Usage

xmu_check_variance(
  data,
  minVar = umx_set_data_variance_check(silent = T)$minVar,
  maxVarRatio = umx_set_data_variance_check(silent = T)$maxVarRatio
)

Arguments

data

the data frame to check

minVar

Minimum allowed variance in variables before warning user variances differ too much.

maxVarRatio

Maximum allowed ratio of variance in data before warning user variances differ too much.

Value

None
